Crowdfunding Platform

I'm seeking a developer to create a crowdfunding platform. Check out these sites for reference [login to view URL] or [login to view URL] as this project will be very similar. Please familiarize yourself with crowdfunding and the many details of this type of site. It's not your average eCommerce project, however simplicity is key in the early stages. These are user driven sites, that allow for timed campaigns, money pledges & transfers (done through a 3rd party), campaign tracking/updates, ETC. I have my own server, so no need to include hosting in your estimate. Also I'm not interested in flash or heavy design work. I mainly need you to code the site, perfect the functionality & user experience, Initial SEO, & light design work. I'm also willing to consider ongoing proposals for site maintenance & upgrades. Feel free to ask me any questions ! I Will pay more for the right person, but you must be able to show me a similar sample that you created or a prototype.
