We currently have an ongoing ecommerce / online auction site built on the phpprobid framework. We are looking for someone to install a php module that has been programmed by [login to view URL] that will allow paypal chained adaptive payments for buyer to seller transactions. The ideal freelancer will be able to understand phpprobid and successfully install the module as well as sync ipn listeners with our phpprobid backend, ensuring proper inventory, transaction and fee updates. We also need to have paypal recurring subscription ability where subscribers to the phpprobid store functionality are billed automatically monthly until cancelled. Phpprobid is built in php / mysql and is currently sitting on a shared hosting service. We expect all work to be completed on the freelancers test server, and no updates should be pushed live until approval. The investor is happy so far with this project and we have additional development projects lined up once we get payment processing working. We're looking for a dependable developer to prove their expertise in phpprobid / php ecommerce programming, so we can continue an ongoing programming and support relationship. Thanks so much for your interest!
