FourSquare, Yelp , Google Place, Google Events, Socialize and other API

Hello developers! I'm looking to develop an app that combine different API's together. Starting with socialize, which provide social activity and user database We will add Yelp API, Foursquare API, Google Events which include almost everything from user comments, location details.. You will provide an admin panel where categories from Yelp, Foursquare, and Google place can be selected as desired. As far as user comments, we can user socialize API mentioned above to create our own comments as well as the original API's user comments. App will be in both Android and Iphone, including Google Map and direction like all other location base app. This location base app will have the capability to show places base on user's location. You will provide detail admin control on choosing category, user profiles, etc.. I prefer to have a team with extensive experience on location base app, google place & other mentioned api app. You will provide excellent portfolio and excellent feedback. We will develop on your choice of service such as google cloud, github, apigee or any other where works are monitor and feedback as it's developing. Please read and contact me before you make any bid, this project will be time consuming as many features needed as far as admin control and user features. I'm not sure if some of the feature can be done but we can be discuss as the project proceed. Thank you all
