I'm not quiet sure what you are asking, since you seem to already know what you want. I'm willing to bet there are more Mom and Pop nurseries in your area than you are aware of. Is there a Grange Hall near by where you might ask someone?
There are inexpensive soil testers that will test for pH, however, you might as well send in a soil sample to have a complete idea of what your soil is like. I think the pH testers you can buy at feed stores are about 15? And the soil tests at the lab are 25 (plus shipping) I think it is worth 25 bucks to know what your soil is really like.

I wouldn't be in a hurry to cut down any trees unless they pose a danger. All tree benefit from annual pruning, but for fruit trees, it is essential.
