Where did you go for testing for your child/children?

My dd#1 (8 yo) was tested 2 years ago by a psychology student at a local college and I'm looking to have her retested. I'd like her tested b/c I suspect she is dyslexic. She thinks outside the box, is a divergent thinker and has anxiety. So I'm not sure if should go with somebody who has experience testing gifted children on a regular basis, or the school psychologist who is used to diagnosing learning disabilities. And if we go with the school psychologist we wouldn't have to pay anything, whereas with private testing we'd have to pay $500 to $1000.
