Ooh... you are north texas. Hmm. The trainers I know are from horse shows so I"m not sure who will be willing to travel.... but here is a website that might be helpful, it's a list of all the trainers who are a member of the tx hunter jumper assoc. Trainers
Take a look and see how's by you. There are A LOT of good trainers on the list. Find a few you might be interested in and I can give you my opinion if I know them.
