I want to apply to YC funding competition, but I'm not a techie. Any advice?

Learn to code. Even if you aren't able to code well enough to build your own thing, if you have not built an application and launched it, you will never be able to manage a team to do it. Much less be able to do with with an outsource provider.

Why not apply to development companies as a programming intern. Explain you're a business guy, teaching yourself coding, you know you'll never be great, but you need to learn.

At my consulting company, we've got a guy who is quitting his job at a VC and working as an intern with us for three months. We do pair programming, so he'll rotate through projects and be on the development team. We won't bill him out to clients obviously. Our developers get to learn about his business experience, and he learns how to code, and probably run a development team.

I tell clients who have an idea and have never built a website to go get a job at a startup. If you're a not a developer, don't do a startup without having worked in one.
