I have a custom made PayPal integrated ad script on my website which i use to sell out ad space on one website.
This is what i need you to modify on it:
1. Correct a small bug in the script, if you extend the length of an advertising spot which was out dated a couple of days ago the script will extend from the time it was out-dated.
2. I want you to modify the script so that i can use it to sell out ad space on any number of websites, advertisers should be able to log in from a "main page" and choose which website they want to advertise on.
Im looking for a experinced coder that is experinced with PayPal integrated scripts.
