Between booking fees, collection fees, handling fees, container fees, shipping fees, return container fees ($350 just for shipping is not out of line). Stallion fees here are starting at $500 so you are getting close to $1000. Then you have the costs for the mare - repro eval, ultra sounds and drugs to bring her in, AI fees, preg checks.... so another $1000. Then you have to look at what comes with that semen - is there a live foal guarantee or are you out the costs if she comes up open? Others have brought up the quality of the stallion - the lower the cost then typically the lower the quality or the stallion is unproven and just starting out so you don't know the quality or characteristics he'll stamp his foals with or whether he inherited any athletic qualities you are looking for, soundness...
You'll be feeding and caring for the mare through her pregnancy - are you prepared for costs associated with the pregnancy - vaccines, feed increases when you hit that third trimester, an emergency before, during or after foaling?
Color wise you are looking at ee?? (AA, Aa or aa) with one Cr for the mare so even breeding to a black you have to understand EEaa is the only thing that will give you a black coat and if your mare carries AA or Aa then you have the chance of of bay. If stallion is Ee then you are looking at the chance of red. So testing for color of the mare is important if you want to guarantee certain outcomes. She would have to be eeaa and stallion EEaa to guarantee black. If you are looking for another palomino then you would have to have a stallion that is CrCr and you open up the possibility of a double dilute. You'd also want an eeCrCr to get the highest probability of palomino... If your primary concern is color then you are better off going out and purchasing what you want.
Having your own stallion to cover your mare? Cheap to breed? Still no, as you now have the cost of another animal to feed and care for in addition to the mare/s. If you want him to pay his way and not count on sales of weanlings or yearlings he has to be promoted or been around long enough to know how those babies perform.
Some horse people change their horse, they change their tack and discipline, they change their instructor; they never change themselves.
