PHP programming 10-15 hour project (estimated)

The website [login to view URL] already accepts paypal. We need you to upgrade the paypal processing to Website Payment Pro from Website Payment Standard. The flow of checkout (you can submit a lead and get a domain and get to payment page without paying anything from home page of [login to view URL]) should be essentially the same as we have now. The difference is that we want a seamless integration using Payment Pro so that paypal automatically debits all available funds sources that the user may have attached to the account to increase the renewals with automatic billing. We have coding that is automated based on the IPN post from paypal for renewals and cancellations of subscriptions so you should make sure our current functions still work. Ideally you already have experience working with PayPal IPN. It's not that difficult though if you are an experienced php programmer. Please 1) Estimate time and cost. Since we already have all paypal code working I estimated about 10 hours to do and test. 2) Please provide similar works with PayPal if you've done them. 3) Confirm you can start right now.
