Android Paid App Marketing/Advertise/promotion

I have Launched a Paid app in Google play Market this month, it's torrent app. I would some one to advertise/market or promote my app..any how i just want users to download my app. i cant pay for marketing only, i can pay only when user will download my app, will pay upto 80% to you. Payment anyway you want. Once per month payout minimum for 100 downloads. It's A very good oppurtunity for you if you are good in marketing. you can earn alot more. Bid for my app Link. Would like to know your Idea too. :) Thanks
