Add Real Time Multiplayer, Game Sounds, Revive Screen Editing with Daily Gift and In-App Purchases for coins in 2D Game

i want you to add real time multiplayer, sounds and in-app purchases about coins for the game. I'll tell the developer that what type of bundles i want in In-App Purchases. This work is needed to be done in few days, may be 3 or 5. The developer has to use Unity3d 5.5.0f3 only for this work along with MonoDevelop or Microsoft VB 2015. (the developer has to tell me which real time multiplayer is performing very good with lowest maintenance and best performance, so i can buy or arrange it's resources). (if developer has been done such work before than, he has to share his any project's apk or play store link, so i can check as well). Note: please bid seriously, as your bids will be considered as your final statement, as i want no work other than i wrote above.
