iso a shetland stallion

so i'm getting ready to unlock my next batch of my shetlands

and found out yesterday, while going through pairs, that i've left one of my girls without a man

portia is the mare

she will be 17 years old when unlocked

(would age the next day, so nearly 18) 

she has 772 overall stats 

your stallion would have to: 

- be 17 or 18 years 

- be in the same discipline (driving)

- have at least 650 stats (but preferably over 700)

i breed at age 20, sometimes 19 if stats are looking good

and/or i want more than one foal 

i would preferably want to buy this stallion so i could keep track of him 

however, i could be open to a private stud 

let me know if you have or know of any available stallions 

by either commenting below or messaging me. 

I have only got private studs, since they are coupled with my own mares. I will keep training/riding lessons with them daily. 
710 stats Silversun 17 years and 2 days till 18, he's paired with a 17 4 days till 18 mare, so it would only be possible if stallion can breed again after one day.
746 stats Frodo 15 years old, so no problems with any breeding at the last day. 
789 stats Kazan 13 years old, will be over 800 when your mare is at max age.
632 stats Special Key 16 years old, perlino, so that's why I am offering him as an option for a nice colour as well.
All four stallions are specialized in driving.
