I'm probably gonna get flamed for this, but if you have a set of calipers, and 
you haven't blown the engine you can do it yourself.  In your favorite shop
manual you will be given the dimensions for the journals at original and at 
all overbores.  It will also give you the tolerance.  Mic each journal on the
crank in at least three different places to see if they are within spec, do the
 same for the rods and the crank journals (on the block).  If they are all 
spec, replace the bearings and reassemble.  If there is doubt, give a machine 
shop the numbers and have them look.  

Ridge reaming and honing if necessary (you don't mention mileage) is real eazy.
Typically if you didn't blow the engine up the rebuild process is pretty easy.

At the very least, if you take the thing apart and take the parts to the machine
shop they can do all the work and you can reassemble.

The parts are real cheap, it is the labor that is a killer.  The more labor you 
do, the less they bill for.  Most of that $3000 is removal, disassembly, 
reassembly, and refiting;  all are very doable if you can follow shop manual
directions.  I personally like Haynes, but I doubt it matters.  At least read 
the chapter on rebuilding the bottom end and see if it is a project you would 
consider undertaking.

A complex system that does not work is invariably found to have
   evolved from a simpler system that worked just fine.
