I just finished my third trip. The first two trip I used Lesley Bruce. Great service.
His quote for this trip was around $300. 8 days. Includes liability. I got quotes from two others that at well spoken of here in the boards. They were over $100 less expensive. I went with one of them.

There are limits to how much a premium you can charge. I would have paid more to Lesley, but not 60% more.
