Intergrate Authorize.net into Xfilesharing pro [XFS]

Hello, We have a secure cloud storage site and we want to integrate a direct Credit Card processing form to the site so that we can sell memberships. In order to do this on-site (without a 3rd party processor like PayPal) we need a payment gateway and a merchant account. - We are looking for someone who has worked with [login to view URL] or CCbill API in the past - You will need to have some Perl experience since we are using XFS script to run our site (XFileSharing Pro) - We also have to use an SSL certificate for the order page (https://) - It would be a plus if you know how to work with SSL certificates as well. In Summar, selected coder will need to integrate [login to view URL] API into XFS as a payment module and provide us advice to complete this task. Most likely we will be using this method [login to view URL] An exmaple: [login to view URL] (you may have to register first) Thank you for bidding.
