I have a current iphone app. It is a game that is priced 0.99. I need somebody to add a leaderboard and work out any minor issues and do some supplementary marketing to start getting downloads. I will pay 10 up front and 30 more after work is all done.
Dear sir
I am mobile game expert , So i have strong experience in leaderboard.
I can integrate it for a short time.
I'd like to discuss with you about our detailed opinion at interview.
Best Regards
