Thanks, folks!
I probably should of disclose more info. I have enough "fun" riding my own horses both are 5 years old and one very high-spirited (I do trail ride and I took lessons in different barn on Jemma - unfortunately they don't have lesson horses there). So it's all very far from "dead broke" only experience.

I was hoping to -start- jumping during a winter on know-the-job horse to prepare myself for jumping with Jemma. And I think the trainer is very nice. But the problem is there are no other horses in barn. Actually one more but the owner states she's worse to ride. Well... Will see. I may just try another place.
