Need someone to write PHP or Ruby for creating a bulletin board. And MySQL expertise is appreciated.

I'm going to develop the interactive business matching website.
The existing business matching websites, like elance.com or freelancer.com, do not have any activity to absorb end users' ideas or viewpoints.
I do want to create the platform, connecting not a client and an engineer, but an end user and an engineer who wants to make products to make the world better.
If you're still interested in this project, please reply to me.
