R Development - open to bidding

Everything needs to be compatible with my game so you will not be paid until it works! heres the things i need scripted if you can do all of these things that would be great: For 2D game Pause Menu: pause button on top right corner of screen, inside of the pause menu should be a play/resume button, also a setting button inside of that should be sound/ mute sound, then there has to be a in-app-purchase button and inside of that is $0.99 for 3 Golden Hearts. then i need you to add onto my MainMenu script in c sharp in-app-purchase button with again the $0.99 for 3 Golden Hearts also i need you to add onto my LevelSelect in c sharp with a way to add my 1 Golden Heart texture so that way it displays 3 Golden Hearts in the Right hand corner. Now in my levels i need a script that shows my 1 Red Heart texture in the top left hand corner and turns it into 5 Red Hearts in that corner so that every time my enemy touches him it takes 1 Red Heart but when he reaches 0 Red Hearts i want it to take away 1 Golden Heart and each Golden Heart takes 20 minutes to regenerate. i want it so the player can't play on any of the levels when he reaches 0 Golden Hearts. Oh important 5 Red Hearts = 1 Golden Heart. The in-app-purchases should work threw apple store +maybe 2 more things
