Write scripts to function Sounds, In-App Purchases & Remove Ads

I've multiple projects in pipeline but first needs to finish my pending project. You're expected to write a script to function Game's Sounds and 5 Bundles of Coins in In-App Purchases and to make "Remove Ads" enable when user click on "Remove Ads" and pay some amount. Rest of the work has already been done so don't worry about it. You must use Unity3d 5.5.0f3 for this work and must deliver in 2 days.
