Enom module for Oscommerce

I am trying to get OSC to work fo rme as a webhost shopping cart. I am needing 3 modules created. At this time an Enom module is most important so this is what I am posting for. I am wanting to be able to purchase domains threw the shopping card useing enom as the registrar. I want to be able to purchase more then one domain if it is so desired by the customer. Also once a domain is purchased I want the client to be able to login to the OSC and change all related domain information. Like regostered Ip, Point DNS, Etc. Right now the only way for this to be done is to goto enoms domain login page at http://access.enom.com. I want to get away from having to send my clients here. I would like them to be able to do all they need to from there account in OSC. I am not sure on how much this would cost. As I am not a programmer.
