I was looking into this before Covid changed the plans. This place looked good and was near the house we were going to rent. https://www.skeabosthotel.com/hotel-services/fishing I have no firsthand experience but this place has more river miles than most others.

I would see if there are any fly shops and get their recommendations. I would line something up to be sure you have a reservation on a beat as they get booked up quickly during the prime season. Once you are there you will get advice from the locals especially if you are not entirely pleased with your original ghillie. Might also check with Orvis and Yellowdog fishing travel to see if they had suggestions.

There are 10 Orvis affiliated shops in Scotland here: https://stores.orvis.co.uk/uk/scotland I would try the Inverness shop first as it is the closest to Skye.
