You will need a Class III hitch, a Class I or II is a tiny 1" X 1" and can't hold that much.
As for brands of racks/carriers, I recomend going to the supermarket and grab a bike mag, there are tons of ads in the back from many manufactures. Or search the web, jo hauler is one I have checked out.
I built my own, here is a photo of my set up, works great!
