I started playing with rails 2 weeks ago.I think I can get an MVP working in rails.The MVP will cost you 200$.It should not have a lot of features just the most important ones.I will not do any graphic design just frontend work with a css framework.You will not have to pay anything upfront.

It would help I you added a link with some previous work (portfolio) from you, projects that you participated or an open source project of some kind that you contributed or started perhaps (if any).
