Well, I'm no graphics artist; however, I would like to help you with a few good pointers for getting the help you need.
First, you need a website. It doesn't have to be fancy, just something that has your contact information, a little about the game you are bringing up to date, and the assistance you would like to have. There are several places to get free hosting (example:
geocities), and, if you are releasing the game as P.D., it's no skin off of your wallet.
Next, take the url to your little site (remember, it does not have be fancy), and make it a news item. A news item will usually get propagated accross several of the amiga-sites, and voila! More bank for the buck.
I wish you good luck, and hope to see your release in the time frame you've allotted to it!
