Rear Main Seal Question

Alright guys, my name is Mike, and I'm a long time lurker to the board, but have owned my 2005 Z71 Ext Cab Colorado with the L5 for almost 6months now. Well, now i believe that the rear main seal is leaking. And leaking bad. The underside of the truck is coated in oil, and its only letting me run about half the amount of oil while i drive it around. Oil light isnt on, but if i have to do a hard brake, the message center will flash check oil then go away. No CEC and no pending codes from scan gauge.

Has anyone had to have there's replaced before? Whats the rough cost of it? When having it replaced should i have the mechanic check for other issues? Should i just look for a new motor? Or should i cut my loss' and sell the rig? Thoughts?
