Build A Site Similar to Propy.com — 2

We are interested in building a site similar to the functionality of Propy.com. This site must also include the ability to buy property with USD and Bitcoin and utilize smart contract technology like Propy.com. An App will also need to be created in addition to the site for Apple and Android phones. Please review the site and submit a bid for our review. I need an estimate on how long it will take to build the site. All timelines will not be released until the site has been beta tested (beta testing will take 30 days). www.propy.com
