Can you camp here with a motorhome and does anyone know how much per night or week or month

Yes, there is camping. It's a state park, so I'd do a search for Georgia State Park campgrounds to find out prices and to make reservations.

Reserve America I believe does the reservations. If you get a friends membership, it includes not only annual passes to save the $5 entrance fee but gives up to 3 nights free camping at any state park in Georgia.

There is priced for primative camping and shelter camping as well as RV and camper camping.

Yes an i font no price, sorry.
