I use Adwords and feel I am very successful with it. I spend about $500 a month and that usually brings in about $5000 - $6000 a month.

Your ad sounds like a scam. Since I don't know what the offer is, I can't suggest an alternative ad.

This one is just another take off on The Rich Jerk, and I think people have seen enough Adwords Ads like this one.
I recommend not going over 10-12 very "tight" keywords and bidding higher. I always bid high enough to be seen on the right hand side "above the fold". (So the viewer can see my ad without having to scroll.) I find the right hand side (first four) performs better than the top of the page "blue" ads. I usually start my bidding at $1.03 and move it up if necessary. Before you decide to change a bid up, let it "sit" for 24-48 hours to see where it settles in.
Your placement is determined on a number of factors....bid, conversion rate, and your overall adwords history. Too many non-performing keywords are going to hurt you.
