Alright, I like the first mare, but I like the sorrel Quarter horse the most out of the two. But it says she's sold.
I can easily see the first mare being 10k, we have lesson/show ponies that can only do flat for 10k.. I'm in Virginia. I DO NOT like the 3rd horse, they didn't set their ad up right, she looks bony & thin, not enough pictures of the horses performance. I like the last horse, but he's not what you're looking for. You want a horse who can "teach", he's a professional show horse who probably needs a rider who can do everything already, no offense. ;]
IF you're interested I have a 13.2 Arab gelding who jumps up to 2'3 for lease down here. I can do something long term if you want..
