Need some small updates in our existing App.

We need some small changes in our existing music App. Current App has lot of offline music files divided in categories, user can play multiple nature sounds simultaneously in loop with timer settings. App link will be provided in chat/after awarding project. Need following updates [login to view URL] and Award- User will be able to share about App in Facebook timeline and view some adv video(you need to setup for advertise links) , once they do, they will be awarded with a download option which once downloaded(download progress will be shown with progress bar,will be in SD card,not directly accessible to user by other media App), open some sounds which will be blocked earlier, in this way we are trying to reduce App first time download size. [login to view URL] sound option in settings which will enable playing sounds with a crossfed with first and last 5% of the sound so that they don't understand gap between loops, also crossfed timer option will enable existing timer play to crossfed last 10% of the time slowly decreasing sound. [login to view URL] page where we will be a able to provide some attribution links (Optional / next update)- Build live wallpapers instead of still wallpaper in sound backgrounds for 10 category pages You need to explicitly provide us the updated code and mention in a document where to modify for what, we will give you free version only to work, as per your document I will update the paid version in my eclipse environment. Don't over bid as these are really small changes, we developed the entire project by a developer in 30$ here who promised us to be available for long term support, but I am not able to reach him now, so there is a good chance if App is successful, we will build up long term relation and we are looking for such a person only who can be available for next update projects.
