As you're (presumably) using prewired pedestal boxes that just need the main feed wires connected and they're good to go, I would not generally expect any electrician to have difficulty. That's not to suggest that checking things is at all a bad idea, if only because everybody can make a mistake or two from time to time.
The main difficulty with wiring RV outlets is with the 30A receptacles. 50A RV receptacles are identical to current 4 wire electric range outlets that any electrician should be familiar with. The 30A RV outlets, though, are superficially similar in appearance to old 30A 240V 3 wire clothes dryer outlets, but unlike them must not be wired for 240V service.
