Hello! I've got extensive experience working in Unity3D, I've developed quite a few games, and a couple of them with source-code is available on GitHub. I'll be available for as long as you want everyday with a maximum of 8 hours, and I'll be available on skype or any other communication media for the duration of the project!
Check my github for some code [login to view URL]
ALSO: If you're interested, just contact me and I'll show you more work.
