Make some changes to my Unity iPhone game via Teamviewer

I have a 2D game in Unity and I need to make some basic animation changes to it. 1. We have a object that is thrown by the character. It lands behind a pile of toys and we need it to land ON TOP OF the pile. 2. We need to rotate an object in the game by a few degrees and make it smaller. 3. Make a small timing change. These are simple tasks and must be done quickly. Freelancers only, please. Since the file is >400MB, it will be best to remote into my server with teamviewer and complete the tasks like that.
