What kind of metrics or reporting are you going to require? I ask because you may not need an lms at all. If you just want to sell the course, I can teach you how to create a time-bound license that will expire, cutting off access. Using a method like this, you can post the course(s) on AWS.
You could still do this and get data back using xAPI (but I'm not an expert here). I would loop in someone like Devlin Peck or Megan Torrance for some guidance if you choose the xAPI route.
Lastly, for a reasonably priced cloud based solution, you might look at Rise 360 or SCORM cloud.
