Building a marketplace platform - Minimum viable product

I am looking to hire an experienced programmer to help me whip up a minimum viable product for a marketplace platform I am currently working on. I have all the designs pretty much completed, and am building the front-end off Zurb's Foundation 5.3, and I can get the HTML to you. I need the backend designed from ground up, including database design/setup, hosting on AWS or another provider, and my basic feature set included in the MVP. Some features include require login/registration credentials, integration with Braintree payments, integration of social media channels APIs, search and filtering, and pulling analytics from other outlets. You WILL be required to sign legal documents upon starting this job, to ensure non-compete and non-disclosure, to be discussed. Interested candidates MUST reply with the subject "LEAN MVP".
