What if I can't find/afford pro designers?

I'm just a college student who thinks coding is fun and wants to build a web app by his own. And learn and do the design by myself seems to be my the only option, since I can't find designers (at least here in China) to be collaborator and do things for free, and I can't afford to hire one either.

BTW, I really don't think "get really good at a web framework in a language of your choice" is the best career advice from one programmer to another.
