Build Web Site

Hello I need something very similar to www. p o p f e e d b a c k (dot) c o m. Please sign up to the site and review in full and demonstrate you have full understanding of the all features, architecture, admin, dashboard, etc. Please advise platform, language you're proposing - open source is preferred. Escrow will be funded in full at the outset of the project and released after proof of fully working, bug free, system. I'm looking for a very fast turnaround but delays will be unacceptable. If you've done something similar, please provide examples. There will be plenty of repeat business for quality work. Start immediately. Please only bid if you accept the following agreement: “The final product will be the sole property of and copyrighted to the {Buyer}. {Provider} will not receive nor request further payments, royalties, or other consideration. {Provider} will not be named as the author or owner of the supplied work. {Provider} expressly acknowledges that the material contributed is being specially ordered and commissioned for use in connection with this project, and is contributed as a "work made for hire" as defined by the copyright laws of the United States.”
