How/where can I get a full body X-ray of my dog?

I want to do an art project with my dog that involves her skeleton(side view). Can I go to a vet and just ask them? How much would it cost? Does anyone know someone in Humboldt county?

She is a very tall dog, weighs about 90lbs, and is not very flexible. She is a bit fussy about submitting to lay down for people, but she doesn’t bite, she is just skittish. I do not want to freak her out, but I also do not want to sedate her.
