The work I need is to get the current plugin working with the Production API keys Get the xcart flow to finish submitting the order to I see it in the back end I will test that the payment shows up in Intuit as well. (decline and successful) I can make any changes or get info from Intuit for you. And you can have FTP to the website.

Full payment will be made as soon as I can test a working product. ----------------------------------------------- General Notes: I'm located in the USA so all communication will be done via Freelancer chat window or emails.
