I will own a site that is a top affiliate DIR and will have all the best affiliate programs on the net ready to promote.
The script: it will be affiliate software,
What it needs to do:
1. Must be able to market other affiliated programs.
2. My customers will sign up and get to pick what affiliate programs they want to promote these programs will be in categories, obviously I will have to be signed up to each one so I will be on the first tear.
3. The custom affiliate software will able my customers to join all the affiliate programs they have chosen within the dir at once.
4. They will then be given rotating banners and links. They must be given a choice of rotation or separate links and banners
This will all happen within the software that you will build it's basically a custom affiliate programme:
once I have signed up to promote an affiliate programme I am given a code I must be able to place this in my admin so it gets incorporated in the banners and texts and email links given to my customers once they have picked there affiliate programs they want to promote. That way no one needs to know and everyone is making money I will just be making more I do hope I have managed to break this down and if any one steels my idea ill come find you 
now if you are a programmer that does not want to work then do NOT contact me i have just had an Indian programmer give e a bid and once I accepted he realized he could not just sell me a script, he then left me hanging! I simply can't deal with this if you don't have the necessary skills don't bid! And if you're going to give me silly bids ill just ignore you, so please just be a normal programmer that understands that I have some programming skills and am fully aware of what things are worth and cost. I simply want someone who is fair and can do the job, I don't care if you have a script that can be customized fine, but be honest and fair. I need a good programmer that wants to earn an honest living no con men just normal honest people need apply thanks.
