Crosswinds is an amazing program! I sold an OTTB to a student in their program and it was a pleasure to work with them. They are very highly regarded among the A level horsemen as well. I’ve always heard nothing but praise.
I don’t mind staying under 2’ on a school horse because I know how important a school horse is and no reputable instructor is going to break down the cornerstone of their living so I can jump higher. If I want to jump higher I can pay to play on my own horse, but I’ve certainly never ran out of things to learn 
Prices I’ve paid in the area:
$55/45 minutes with a BNT (leaving out the details to protect the innocent but really a proven horsewoman)
$40/45 minutes on a school horse with someone who has made more progress with my equitation in 3 sporatic lessons than I would have thought possible. She actually ocassionally posts on my Facebook with encouragement and exercises - a TRUE class act!!
By comparison in Iowa, expect to pay $55-75/45 minutes on your own horse.
As an aside, my horse’s half sister (same dam) is a school horse and shows the A and B circuit with students. I refuse to believe this is a rare occurrence. I can’t imagine its cheap to do so - but no one ever said this sport would be cheap. A horse that can complete at that level and teach is nearly unreplacable. (Fun fact is I sold the mare dirt cheap because she just wasn’t big or fancy enough fresh off the track for most buyers, I 110% respect the 2 well regarded pros who saw her value).
OP - sorry this thread has been hyjacked - good luck again in your search
