Location based mobile social network

I am looking for a developer to develop a location based social network for Android and iOS devices. It may be a modified/rebranded version of Boonex mobile apps, if you have the licence already. You can view the application on iStore or Android market. Alternatively, apps you have already developed are also welcome. My budget is tight so you may rebrand and sell your existing app if you are eligable to. Appcelerator Titanium based apps are also accepted. I need the features of Boonex apps with: - Rebranding - Registration and Login (instead of Boonex's own login) - No "sound module" - Ad placement - Simple Question&Answer module for members - Compilation & Submission The members must be able to invite friends by their e-mail and by using Facebook API. For server side programming you may use the open source php script of Boonex. Please type the keyword "LBSN" within your bid. Thanks
