Looking for horse to care for, or half lease

 My 13-year-old daughter would like to find a horse to help care for, or a half lease. She has had several lessons, and loves it very much. (What's new, right?). 

She wants to be a vet when she grows up, and wants to spend lots of time with a horse, feeding, grooming, etc. I will get her a horse of her own someday, but I prefer not to do that quite yet, until she's had more experience and is sure she will stick with this.

Marianne is adult size (5'8" and ~130lbs) so she would not need a small horse or pony.  We live only a few miles away, so she can get there frequently.

Thank you, amya54
