Horse Help Needed

I was wondering if people could help me in improving my horses and maybe tell me why they dont sell or no one breeds to them. 

I currently breed for - 

Western - Paints - Line/Foundation 
Western - Silver Quarters - Lines
Driving - Creme Gypsys - Lines/Mostly Foundation 
Jumping - Trakes - Mostly Foundation/Lines

Thank you for your time. :) 

I did not look at all of your horses but it seems like a lot of them that I did look at had very high non-specialty stats. There is a discussion here that is not speaking of you specifically but may be helpful in understanding why your horses are not selling.

As far as improving your horses, how do you mean? What are your particular breeding goals?
