Intake Manifold Gasket Replacement

What is your question?

My 2004 C230 has 57,000 miles on it (Pacific Northwest)and it now needs the intake manifold gasket replaced. I don't want the dealer to do the repair for obvious reasons ($$$)...Can anyone give me a ballpark cost for a qualified mechanic to replace my gasket? The part is less than $10, so I know the cost is pretty much all labor...thanks in advance for your help...
