Advertising manager

I need someone able to help me to advertise my product, an php script for domain owners, and raise my sales. I would like an 10-day free test demonstration of your abilities. I'll pay only the money you need to pay the ads price (for example: [login to view URL] banners, google adwords, etc.) If you can do some really good sales, i'll hire you as my company marketing advisor. I need a really good marketing plan.
