We need to create a facebook app similar to the one at:
[url removed, login to view]!/apps/[url removed, login to view]
Please install it, work with it, and then let us know the cost of developing such tool.
Please do not bid before you check it properly ok?
We will only assign this project to a freelance or company with proven record of developing flawless facebook apps.
If you can also integrate twitter in the app, and eventually create something similar for iPhone, that is a plus.
