Advertising jewelry online store.

I'm looking for someone/team who are very confident to advertise 'Online jewelry store'. the website makes 1~2 sales per a week. the price range of our products is $100~$300 USD. now I need to make it at least 5 sales per a week. you can use any methods. you must make at least 5 sales in 2 weeks. OTHERWISE YOU WON'T GET PAID ANY. if it is success, I'll pay $150 and extra $20 per an item from the 6th sale. for example, if you make 7 sales in 2weeks time, I'll pay $150(5sales) + $40(extra 2sales) = $190. however, 4 sales won't give any. (because there are some sales already at the moment.) bid with specific description of the method you are going to use. our website address will be given via PM. Thank you.
