Up until working with Casey, we had only had poor to mediocre experiences outsourcing work to agencies. Casey & the team at CJ&CO are the exception to the rule.
Communication was beyond great, his understanding of our vision was phenomenal, and instead of needing babysitting like the other agencies we worked with, he was not only completely dependable but also gave us sound suggestions on how to get better results, at the risk of us not needing him for the initial job we requested (absolute gem).
This has truly been the first time we worked with someone outside of our business that quickly grasped our vision, and that I could completely forget about and would still deliver above expectations.
I honestly can’t wait to work in many more projects together!

Got Your Blueprint?
G’day, I’m Casey Jones.
Let me ask you a quick one…
Are your digital marketing efforts delivering the leads you need for your house extension projects? Or are you watching rivals snag contract after contract while your schedule stays empty?
The online marketplace for house extensions is tougher than ever.
Budgets are tight, competition is fierce, and every lost enquiry is a missed opportunity.
If that sounds familiar, you’re not alone.
Maybe you’ve tried standard ads or built a website that just doesn’t convert.
You might have dabbled in social media, only to see underwhelming results.
That’s why you need more than another run‐of‐the‐mill agency – you need a partner who understands the unique challenges of the house extension market.
At CJ&CO, we help you to spotlight your brand and secure project enquiries – whether that’s through targeted SEO or precision PPC. It all starts with a no‐nonsense chat to see if we’re the right fit.
No fluff. No pressure. Just real talk about unlocking your growth potential.

After countless attempts with other companies and always being left disappointed, finding Casey and the Team has been the biggest blessing. The quality, knowledge and professionalism is second to none. I’ve since engaged CJ&CO for the design and build of 2 of my business's websites and ongoing SEO works. Couldn’t be happier with the service and care I’ve received since day one! Special thanks to Casey and Mits! Would and have recommended to others!
Working with this web designer was an absolute pleasure. The entire process was seamless, easy, and incredibly user-friendly. They were patient and flexible with all the changes and back-and-forth, and their communication was always prompt and professional. Most importantly, they absolutely nailed the brief. I couldn’t be happier with the final result — highly recommend!
Communication. The communication between CJ&CO (particularly Casey and Mits) was quick, clear and provided easily understandable information. They balance patience and walking their clients through the journey with efficiency really well. They understand how to directing the Client based on their learned experience whilst being open to Clients ideas resulting in a superb end product. Highly recommended.
CJ&CO did an amazing job creating my website
Working with CJ&CO was nothing short of exceptional. From the very first conversation, they understood exactly what I needed for my website and brought it to life with precision, creativity, and a genuine care for the brand vision. The final product exceeded all expectations, both visually and functionally. Casey and Mits were professional, attentive and genuinely invested in bringing the site to life It was a seamless experience from start to finish, and I couldn’t be happier with the result.
I'm completely impressed with the professionalism and customer services. I feel very confident and satisfied that my web page will have and awesome outcomes. Their staff is not only friendly but also highly skilled
Great service, fantastic website design and reliable team.
We had an excellent experience working with Casey and Mits. Their expertise, thoughtful recommendations, and keen attention to detail stood out from the start. They took the time to fully understand the scope of our project, and the final outcome met all our expectations — delivered on time, on budget, and to a high standard. Communication was consistently clear, professional, and impressively prompt. We highly recommend their services!
Friendly staff and professional practitioners. Updated and informed along every step, absolute pleasure to work with. top quality result’s, Love it!
Amazing team of web developers made the process of creating my first website easy and made exactly what I wanted and needed
To the insightful marketing behemoth that Casey brings to our whole world of getting in the customers focus zone, once again your insightful strategies always go above and beyond the normality of blanket marketing and get us some enviable results from our competitors and partners alike. Keep up the efforts mate. You are our connection to the customer.
The enquiries just keep coming and the business is now unrecognisable. But, what we like most about Casey, is he's a great communicator, really easy to work with and responsive to our needs.
CJ&CO has helped me to steadily gain clients so much that I'm now looking at taking on additional staff to meet the demand.
I'd highly recommend Casey to business owners who are looking to take that plunge to market their business online.
Within a very short amount of time, the leads coming in the door were AMAZING!
My business is thriving. They developed a new easy to use website for me whilst also managing my Google AdWords account.
I used to enjoy doing my own marketing. Landing leads and cinching clients is a real endorphin rush. However, it was very hit or miss. One day, something changed and after almost $300 in Facebook ad spend, I didn’t land a single lead. I couldn’t figure it out and got referred to CJ&CO from a fellow OT. Within a month, with Casey's short-term strategy, the leads were rolling in!
