Questions I often get asked.
Can't find what you're looking for? Get in touch directly, I always reply within 24 hours.
Get in touchA business website usually takes 2 to 4 weeks, depending on how quickly you send feedback. A more complex e-commerce project can take 4 to 8 weeks. My process is built to move fast without ever cutting corners on quality or SEO.
I don't just 'make a nice website'. I deliver a tool built to turn your visitors into clients. My websites are extremely fast, fully optimised for Google from the ground up, and use high-end designs that set you apart straight away. The initial investment pays for itself through the extra revenue it brings in.
Absolutely. Once the website is finished, I give you a clear, simple admin interface. You can easily add articles, edit your text or swap images without my help. A short training session is always included too.
Yes. Typically, I ask for a 50% deposit when the project starts to reserve my time, and the remaining 50% when the website is delivered. For larger projects (SaaS or major e-commerce), a three-instalment plan can be discussed.
I'm still here. You can make changes yourself through the simple admin area, or bring me in at my hourly rate to add specific features. I also offer maintenance plans if you'd rather hand over all the updates and security.
Still not sure I'm the right fit?
Let ChatGPT, Claude or Perplexity look at my work for you. One click, an honest answer, and you decide with confidence.
