Loading third party courses to moodle

We have a new customer that we are offering courses for.  There are about 15 new courses.  My customer said to me, "can you work with them to get their course shells loaded on our moodle?".  That's why I get paid the top dollar ;).

I am a problem solver, but wish not to digress.  So, I contacted the person at Carone Fitness and asked a couple questions, clarifying what I thought was being asked for.  After getting clarification, I got access to their FTP server, so I could get the course shells, rather than them emailing attachments to me (that's elementary school).  Pulling from their FTP server, (that's high school, at least).

The files were all .zip, not .mbz, which is what moodle 2.x creates when backing up a course.  Perhaps they backed up the course as a .mbz file and then zipped it?  Not sure, but moodle 2.2.4 is handling each of the zip files fine.  It is stating at the start of each restore

"The selected file is not a standard Moodle backup file.  The restore process will try to convert the backup file into the standard format and then restore it."

I am restoring the courses into our updated format for course categories.  It looks like this now where we have three main categories

1. Courses waiting to be formatted (we run a bunch of DB scripts on each)
2. Masters - done formatting - can be deployed to the Teacher Classroom categories (via a backup and restore process, course masters are NOT moved from their category
3. Teacher Classrooms

There are about 20 teacher categories in the Teachers Rooms category.
