Some providers give advice and leave the build to someone else. Others build what you specify without testing the brief.
As your advisor, I help you decide what is worth building, what it needs to do and what it will cost to run. As the builder, I build the website or the tool from that plan, test it against real work and hand it over.
Your proposal identifies what you own, which accounts you control and what it costs to run. Website care is optional. Applications have an agreed operating plan, whether I support them or hand them over to a qualified provider.
The comparison on the Services page sets advisor only, build-only agency and advisor and builder side by side.
