70434 Counter Service Script

I would like to have a counter service script developed that will allow people to sign up for their own free counter for their website. In addition, I require an upgrade feature that will allow members to purchase a counter that will remove the link back that the free counter will provide. The scripts must come with non-exclusive distribution rights - PayPal IPN to to upgrade. - Admin area fo moderation - PHP/mySQL - Members area where they can modify their account info/upgrade. Demo's must be provided in the PBM for exisitng scripts that include admin info. Also you must be the original author. Any pirated or reseller items that are presented must include owner contact information to confim it is not an illegal copy.
