264151 GeoDesics Script Change

Looking for a coder who is familiar with geodesic software. We are wanting some script changes made. WE are looking for some to change the code on the subscription so it auto bills the customer everymonth. As of right now the customer has to make the payment every month. We use paypal and paypal already has a subcription service but I need it to work automaticilly with our site one they sign up. Thanks Nate
