Most of the apps will be games , you might need to change main character , menu style , ingame background , add sdk like chartboost or admob etc and icon ,
any two from above should be done per app
I need some one who can do this and deliver one apps per day ,
I will provide the source codes
Please quote a flat price per app , This will be a long term project . .I have reskin graphics collection you can choose characters , backgrounds etc from them
