The app （similar to Craigslist) I am creating will have capability to: -allow user to create profile or use existing social media accounts Facebook, Google+, LinkedIn -post (like craigslist) -user profile can be created and managed in this app -rating system for other users -allow users to book mark posts -leave public or private comments under a specific post -payment through internal points, creadit card or app store purchase. - identify user location and calculate distance. I have specification and PSD mock up screens (totally 19 pages). I need trustworthy front end and back end developers. Or someone can do both!
