You can buy a lot of books for the money that testing will cost.

In your situation, if I were to test, I'd be sure to find someone with expertise testing gifted kids. Your daughter's WPPSI results may also have been depressed by inexperience of the county tester. Based on what I've read (keeping in mind that I'm a non-expert) I would stay away from testing by students or interns, etc. even though it may be a lot cheaper. I'd also make sure that your tester uses modern tests.
