To put it bluntly, you're looking for an artist to work for you for free without you giving them any form of substantiable return?
As someone who's been there before, let me give you some advice:
Before you waste your time posting things like this, go and make your game using free/ripoff assets from websites such as this and other games. It looks like you're planning to make money from this, so when the game looks good with free assets and you have something to show, invest some of your own finances in a good artist and commission some artwork for your game. Afterall, it is a business and you can't expect to get anything in return if you haven't invested any yourself - you can't go around looking for voluntary work in something you want to make money out of.
