Do you already have the pedestals set up, like with boxes?
If not, you can buy the outlet boxes for rv's that are already pre-made that have the 30 amp and 20 amp outlets already installed in them (along with circuit breakers). You can buy these at Home Depot, Menards, AMazon, electrical supply houses, etc.
You then only have to run the supply/feed wires to the boxes, as they are already internally wired correct for the outlets.
You will need to make sure of the supply wire sizing to the outlet boxes, as well as what you are using to provide the electrical supply/feed to the pedestals.
I'm not sure of what kind of power you will need to supply ten sites. This is where the professionals come into play, as in an electrician (one with experience in wiring a series of pedestals) and your electricity company.
When I was adding a detached garage (with air/conditioning) beside my house, I had a guy from my power company come out first. He was able to tell me if I could tap off of my house or if I needed to run another power line into it. The good thing about this guy, all his advice and recommendations were free. IMHO, your electric company would be the first place to start.
EDIT: I see where Lou and Joel answered as I was slowly typing away. LOL
