We will be in Moab next month and flying out of Grand Junction. Favorite shuttle/limo companies in the area???
I looked at Moab express it will cost $350, most other companies want you to call/email/app and give them your phone before they'll quote you a price. I'd rather pick a place first before I give them my numbers.

That's nearly 120 miles one way -- $350 seems pretty reasonable.

Have you looked at flying? There might be a small plane that does charters from Moab

Well inflation I guess. We live 100 miles from JFK (New York) and our trip was $220.

It isn't just about the distance. The the NYC area is a whole different kettle of fish. Car services travel to/from JFK/LGA/EWR multiple times every day. Doubtful there would be any deadheading one way trips. Moab to/from GJT which only has a handful of commercial flights a day, could often be an empty drive back, thus higher rates. Especially since probably 95% maybe more of those arriving will either rent a car or be on some sort of tour.

Have you considered a one way car rental? (Although I just did a dummy booking on Enterprise, and they don't have cars available for one way drop off Moab-GJ, at least for the dates I used).
