Reskin a sudoku game

I just bought the source code for a game and need it entirely reskinned.

- provide all the art related to the game (change based on the inspiration image provided)
- reskin the background and the buttons, sound.
- reskin all numbers font
- interstitial ads working (Advertising integration)
- building and testing
- integrate Mobile Push Notifications with Amazon
-generate 1,000,000 sudoku games (have the engine for this ready).
-compilation and help submit to ios/android store/web.

My budget is at most $450 for all of it. Please if you are going to ask more, do not message or bid. Thank you!
