I need a website/webapp developer for creating a teacher/students marketplace

Hello,

My name is Alexis Frenkel. I am an entrepreneur from Córdoba, Argentina looking for enthusiast website programmers/designers who are willing to receive my instructions in order to create a web platform to join demand and supply from my service on one single place. I want to have the supply part ranked by the users who used the services from them, and also expect some kind of link to the linkedin/facebook API.

My expectations are:
- To create a modern, well-design front-end.
- To create a solid and understandable back-end.
- To have well-organized programming in order to make it usable by any programmer in the future.

Please comment me your skills and offers so I can evaluate my convenience. I also need to review your related portfolio.

Thanks,
