Chris, its not really any harder than 110 once you understand the wiring principles of 220. Just check your local codes for placement and distance from your hot tub (water source) and do it. If in doubt use the next heaver gauge wire for any given distance. And I would place an outside breaker near the tub whether code calls for it or not. Just easier in the long run.
