Sale & marketing of Arcade Script

@@@@@####### Please read complete Job description before you Bid #######@@@@@ From 2012 i am selling my php arcade script(which costs $49) online with my website. i am not doing any marketing or seo, so i have very small traffic with few sells a month. I want a professional online marketer who can sell at least 30 scripts for me in a month. i will hire successful marketer for 6+ months to sell my product. Please note some points before you Bid. 1) I will release your first 25% milestone after 5 successful sales, 50% milestone after 20 sales & remaining 25% milestones after completion of work. 2) I will pay bonus amount if you sell more than 30 sales a month but less than 60 sales. 3) I will pay double payment if you sell 60 sales, same for 90, 120 or more. Means more you sell more you will earn. Remember 30 sales is the target of this project, less than 30 means fail project. Don't worry about product, it a good product. i already sold it to more than 30 customers with good feedback and without any complaints or any refunds. Thanks Ajin
