channel manager booking

Hello everyone, I'm developing a php booking software for a customer. I need someone to give me a hand in the development of part of the application. The work would be to create a channel manager, who knows the area knows what I'm talking about, trough my interface the customer can update your account on portals such as venere, booking, Expedia, [login to view URL], metravel, or even only some of them. Bye, Dario
