COM DLL for scripted interaction with XML cmds sent tosocket

For Freelancer1977 Hi, I need a COM DLL which will allow interaction with Inepro UIS through XML commands being send to a Socket. The DLL will have a Customer and Terminal interface in it as well as the ability post a sales transaction using a TransactionSession interface which stores up transactions using the AddTransaction Method and then processes them after EndSession. The Customer interface will also expose TenderPurses The interface should work as closely to the existing interface as possible, I understand that some of the data retrieved using the existing interface will not be available and should this be needed then a change will be raised for this. Examples of how the current interface work are available. The Budget for this project is $750 and the use of milestones is accepted
