How big of a game are you looking at? Most flash games are made by only one or two people. If two people then one artist and one coder. To be frank, your game is very cliche, top down shooter and zombie theme, and your credentials are lacking quality.
Don't let me stamp out your hopes; there might be a someone out there willing to help you, but I am just saying what everyone else will say in a nicer fashion. Good luck with your game and practice practice practice :).
