Moodle jobs

We currently have two LMSs on which our online education is offered. One we own, and one we lease. We would like to explore hiring a development firm with a presence in the United States to build the LMS that our customers want and need using Moodle as the open source foundation. We will need ongoing support after the LMS is built, so we will need to feel secure that the firm we hire will be around well into the future. Two of our uses of the LMS are e-commerce. On one use of our LMS, we give unlimited use to the employer and invoice on a monthly basis.
