eBay Deal

Hi, I am contacting you regarding a deal on eBay. I am a new user and i have 0 feedback. Iwould like to know if you can help me selling an item on ebay because i saw you have a positive feedback.I am asking this because i am afraid i could get scammed, since i am a new user. In exchange i will pay you 20% from the total amount, in case my item will be sold.If you agree let me know and i will provide you the pictures and the details of my product. Email me back if you agree. Thanks Chris
