Before you get too far into the REAR MAIN SEAL REPLACEMENT procedure,, have you eliminate ALL the other common oil leakage issues that MIMIC a real seal issue,, like:
- Oil Sending Unit Sensor leakage (VERY COMMON ISSUE)
- Valve cover Leak
- Valve Valley Cover leak.
Im doing a clutch replacement and before I tore down my drive train, I had a trace of oil coming from the block / bell housing area.
Upon teardown I found out it was a very slight leak around the oil sending unit.. The rear main seal was fine.

I did one myself and it's a pain in the butt. I had some other things to do, (oil pan gasket, trans rebuild) so I did this while I was there. It took me over an hour to pull the seal, even staring right at it. The service manual says gently pry it out. Well, I broke a screwdriver and stabbed my hand, while gently prying. 
I drilled into that sucker, inserted a screw, and pulled it out. Win!
I saved $2000 according to your quote, so I guess it was worth it. This is what my stuff looked like under construction. Gives you an idea what you're up against.

Dropping the rear cradle, tranny, and drive shaft is a lot of work. If you determine for certain that is where your leak is from, I recommend ordering the rear cover that has the new seal installed in it. It comes with new bolts and cover gasket. I think I paid about $65 for it.
Spray the area good with a brake cleaner to get rid of all the oil and see if you can find where the leak is from for certain.

You don't want to do a job as involved as that one will be,fire it up and go "Well,that wasn't it!"
It may take a few hours to determine the actual source of the leak,and you may find that it is,indeed,the rear main-but if you find it isn't,you just saved yourself minimum 12 hours of work.

Thanks everyone, I would do it myself, but I can't afford the time, plus don't have all the tools. I better let the pro's handle this one. My level of expertise is replacing easy bolt and screw parts, water pump, thermostat, belt, brake pads, etc.
by the way does anyone know about this link:
