Recently we had developed a live music even promotion and artist hiring script using php/mysql. I am planning to sell exclusive right of this script as one-time sales using bidding system. See more details in our blog post. Even I listed it in Trade section of DP. But till now I am not getting any suitable quotes even when people are saying that this script is interesting and excellent. So, I am planning to use affiliate system to sell this script. I am planning to give 50% of the gain as affiliate commission to the person who refers highest/winning quote. Gain will be calculated as Winning quote - starting price. Starting price is 275$. So, if an affiliate refers a buyer who gives quotes of 475$. And if this quote is selected as winning quote the gain will be 200$. So the affiliate will get 100$ as commission. I am searching for a affiliate system to implement this. Let me know if anybody knows such a affiliate system. And you can PM me if you need more details about this script if you want to do referral for getting the 50% of the Gain.
