Arabianequine,
As far as finding a trainer, ask ask and ask. I'm not in your area so I don't have recommendations on a specific trainer. Again, check out
www.arabianhorses.org for Arab trainers on there. If nothing else, it might put you in touch with someone who knows someone. Things like that have happened to me before. I posted an ad in a Michigan magazine for a half-Arab mare for sale that I was selling for a friend since I had trained it. A woman called on it, wanting the horse for her granddaughter. I knew the horse wasn't suitable for a beginner, but I did know of someone who was selling a kid's safe horse since the rider had gone off to college. She ended up buying the older kid safe horse.
Another case in point, when I was selling my Arabian mare, I replied to a CL ad that was a horse wanted. Woman said that my Arab would be a bit too small for her, but she had a friend with a 12 yr old daughter that wanted a horse that she could trail ride with and do small shows. The people with the 12 yr old daughter bought my horse.
So much of the horse world is a network
--Hang out in tack stores, look at the bulletin boards there
--Check out dreamhorse.com for trainers
--Again, the
www.arabianhorses.org Go to mentor network, boarding stables, and Arabian farms for possible leads
My degree is History and Spanish, so I personally love to research ANYTHING ... but do your own research, make calls, ask, look, heck even google "Arabian horse trainers Washington State"
But YOU have to find the trainer, none of us can do it for you.
