Tanks 4 live rock ?

[finfan4]

I have 2 A.G.A 38 gal tanks that i would like to trade for some live rock. tanks are 36inch long, and are less than 1 year old. Sorry, not drilled. Im trying to get enough rock for my 55gal. Im not sure what equal value would be , so if you r interested lets talk. Thanks for looking.
