Alternative marketplace for android users

Hopefully with that title you understand what your setting out to do. i will explain in further detail about this when you contact me heres some basics.. Basically i want a android market replica and its going to have to have an extensive backend and actual application. If you have an inteam graphics design team that would be excellent but if not please tell me so i can hire one separately. Its going to have to communicate back and forth with the server and its going to have many features which we will discuss in full when we discuss the bid. It has to have a very stable backend as our current application already has nearly 2million users. So HUGE loads should be anticipated and expected. Varnish knowledge would be suggested since that speeds things up incredibly. the backend will need an admin interface and user interface so i can personally go in and manage all the applications that have been uploaded. plus users need a place to upload apps and i need a place to manage user accounts and manage applications information etc. It will parse apk data from sites such as [login to view URL] and [login to view URL] if you do this succesfully i will gladly rehire you to do a [login to view URL] replica to work alongside the application. We will get into more specifics when we talk. Basically.. heres the things -Application -Design -Backend -User Backend -Admin backend -Advanced uploader with parsing and automatic filtration systems. -Stable backend that can handle terabytes of data downloaded daily from millions of users.
