Build my website from scratch

This will be a network of sites. There will be one (1) main site and twelve (12) sites independent but connected to the main site. For example: [login to view URL] is their main site and sites like [login to view URL] and [login to view URL] are examples of their "independent but connected sites". Rivals does the exact same thing we will be doing. Another site to reference is [login to view URL] and their connected sites such as georgia.247sports.com. I need: videos (some subscription based) message boards (some subscription based) podcasts (some subscription based) articles (some subscription based) ability to link to facebook & twitter real time ticker flowing for all information that is coming in from social networking site like twitter and facebook (subscription based customers only) ability to take payment via credit card site must be secure ability to see where people are logging in from and to detect when more than 1 user is using the same password from different locations at the same time the ability for me to see a chart of who joined the password protected site that day/month/year and who canceled their subscription that day/month/year (where is the income coming from) I need to know where the subscriptions are coming from -- which site is doing what (each site will have it's own subscription base) I want the site and message boards to look very clean and have the most up-to-date software I am brainstorming right now so there may be other stuff I just want to be clear as to what it is I want from this -- it must be first class with no bugs I hope this helps -- again, there may be other stuff I want done also, please know that this will be an ongoing relationship -- I will need support going forward from the company I choose Payment will be 33% up-front, 33% in the middle of the project, and the final 33% at the end I would like the project done within 2 months of the start date Please look through the sites I have provided for reference as they will give you a good understanding of what I want/need
