I need someone to modify my autosurf scripts to add the 'sell credits' features for members. Selling credits should be automatic within the site, meaning credits will be deducted and members autosurf account are credited with the money. I also need to be able to set the daily limit for credits I will buy from members. Prices for the credits must be easy to set thru the admin panel and must support different pricing for different member type. + minor fixes for my pixel scripts.
