Well these guys are probably the best you will find, period- The Perch Patrol. Check out their website, I believe it is
www.perchpatrol.net. I don't know the going price for a guide at all, but obviously I am sure they are more expensive than others. Everything is provided though, Trap, Vex, etc. I don't know what you are looking at bringing, but I'd go with them for my first time. I am sure there are plenty of decent guides out there though.
