Eric Prey is one of the best on the lake. My son and I hired him in early July, and we crushed them. If you're staying on the lake, he will pick you up at your dock.
Fish Taneycomo instead. You can rent a boat, start at the dam and just float down fishing with power bait. Spent many summers going up there and limiting out on rainbows and browns.
I highly recommend Mike Boyles on Table Rock. Wife and I caught 38 smallmouth with him in the summer a couple of years ago! High energy guy who will target whatever species you want. Lots of smiling kids in his photos!
