Although deryk's thread certainly borders on a spam, since it is presented as a question --- I shall respond.
Obviously there is a large group of musicians (as indicated by this site) who are in search of the best recorded sound - and some of them may be looking to turn their little home studios into a source of revenue.
However, although Full Sail and like schools do charge big bucks - to give someone an in as an assistant to the assistant - the fact is they provide hands on to the kind of gear used in "real studios" and they do provide training in the audio/accustic formulas needed in the recordng and audio production world. In fact many would not even get in the door of a recording studio without that diploma. By the way, based on many discussions I've had - many of the students from these schools get jobs at technology firms - which pay much better than $5 per hour.
Only you know what your credentials are to qualify you as a teacher (I'm assuming you have succesfully run a $25 per hour studio and actually are a pro or semi pro engineer/producer - or you wouldn't /shouldn't be thinking about "selling your knowledge").
However, as I figure it, if you charged $2000 for an eight week course (two nights a week, 4 hours per night = a total of 64 hours which comes to $31.25 per hour). I would then need to book 80 hours of studio time at $25.00 to pay off the "tuition" - which may be only one or two projects. Now on the surface the $2,000 seems like a real fair price - but many may not agree.
Although I've already learned most of what I need to run my $25 per hour studio (I'll never know all I need), I would have been willing (at a earlier point in life) to spend a few hundred for such a course (but probably not $2000). Keep in mind the people who attend Full Sail are looking for a career, not a hobby.
If you're looking to provide knowledge, just cause you have it and some need it, it may be a fun thing to do. But my gut feeling is, most people would rather spend the $2000 on gear and figure it out themselves.
