What is the best way to get tow hooks for my jeep liberty?

I want to take my jeep liberty sport to the sand dunes and Ive been told I should look into tow hooks. How much should those cost? Where would be the best place to buy them? Should I install them myself? Is there anything else I should know about the dunes other than getting my orv sticker?|||Check out http://www.jeep4x4center.com/|||try the 4x4 websites and look up your vehicle to see if they have any. I'm sure they do, and second with a liberty you will get stuck.
