guaranteed signups/guaranteed sales

Hi there, I am looking for someone to help me get sales for a number of my on-line businesses I currently have, they include Amazon web stores and on-line web service companies, for the person I find if we work well together it will be a long term business arrangement so keep that in mind when you are bidding for this job, for those who wish to apply work examples and references will be important and it will greatly enhance your odds of getting the job, I will pay via PayPal for every 10 or so sales you generate for me, so when applying for this job can you give your price per 10 sales and a time frame and remember this will be long term for the person I select, I can give you more details if you need them so just send me a message if you need anything, thanks
