"What would you do?"

First I would get on his case, tell him the website needs to be updated because the service will not grow into a real business in its current 1990s design. Show him websites that I feel are a good standard and what I expect our site to be like. If he can't do that then it is the wrong partnership for me.

I would stop working on the project(in relation to his ideas/feedback/requests), tell him I need the website updated a few decades or I'm on my way.

and then plan do the whole thing on my own while keeping an eye out for another co-founder with some technical ability aswell as business interests.

You should take the positives out of this project in its current state. You have the technical side down and you know you can get customers to pay for the service.
