oreo, I also wanted to say to check Groupons. The barn I keep my gelding at does dressage lessons and camps during the summer, they have offered a couple groupons over the years and it's dramatically less than their regular lessons. I've also seen other dressage trainers, and saddleseat trainers do this. I would say right now for you, discipline isn't of importance, basics are basics

There was a point when I was 14 or so I was taking lessons twice a week at a hunter/jumper barn (I worked those lessons off by helping with stalls and cleaning tack and longeing horses for the trainer there, so even when I was working, I was learning! it was a GREAT situation), and then once a week I was riding at a saddleseat barn, and THEN I was riding with my cousin on the weekend on her western trail riding farm Even though what I was doing at each place was drastically different, I sure learned a ton!
