Probably depends a lot on where he will be fishing. I used a guide in Colorado and although I had my own gear (waders, rod, etc) they elected to furnish everything. They had a big enough selection that sizing was no problem. A few weeks after my trip, I got a notice from the outfitter that they were selling off that season's rods, waders, et al. This happened to be an Orvis store, and they had some pretty good deals on the equipment. I'd think he'd be able to get set up without purchasing anything if he checks around to the different guide services, etc.
