One of the few downsides to living in a rural area. A casual drop in would require 3 1/2-4 hours of driving, so I don't think that's going to happen.
But 1st read and watch videos. Google is your friend. There's plenty on the interwebs posted by pro fitters, read all you can find. Watch their videos.
2nd, play with the different positions on your current bike. Seat up and down, fore and aft. Raise and lower handlebars/stem. Cheap stems of different lengths longer & shorter, depending what feels right.
Ride bike on trainer in front of mirror and with partner watching. Change what feels like changing or what looks "wrong" and ride some more. Ride on the road, how do the changes stack up? Repeat.
When everything feels good then call and talk with fitters, get a feel for their take and decide if you want to take the drive.
Or, take your measurements and and transcribe them to the geometry charts of the bikes that catch your eye. What frame size of the brands that you're considering can match your measurements with a stem length and seat post extension that suits you.
If you can find what works on a too small or large frame those numbers can be transcribed to the correct size frame.
