Hey HN, I'm 16 -- and I've been wanting to do a internet startup, but I don't have starting capital so I'd have to find a php developer to partner with.
http://builditwith.me is kind of a cool place to find partners, you can search for people looking for designers etc. Do you have any of your work you can show people? That's usually something they look for, I look for. Even if it's not an actual site, just a psd mockup, you should have something you designed.
Not to start a flame war or anything, but have you looked into Ruby on Rails? Aside from the fact that you need a hosting provider that supports RoR, it's a great platform to get things moving quickly.
Im a programmer and social entrepreneur whos always looking to connect with other programmers. I might know of some people and places where you can find people your age. What is a contact for both of you?
I'm a software developer and would potentially be interested in helping you (or anyone for that matter) out in terms of getting a basic product / prototype developed. I'm always looking for new projects to spend some time on.
Lets talk, fill this form out and I'll be in touch :)
