ISO High Stat QH Mares

Looking for a couple high stat QH mares for my breeding project. I will be picky as to what I buy as there are specifics I'm looking for, some of those are....

1. Stats must be over 600

2. Prefer mares to be over 14yrs old but will look at younger mares if they meet other requirements

3. Must have clean lines

4. Prefer never bred but will consider low foal mares

5. Must be trained in Western, prefer never converted

Please post links if you think you have a mare or two that I would be interested in
