The compressor isn't a terribly difficult rebuild that requires few special tools to accomplish. The required kits are very available, inexpensive and something to consider. Cleaning, preparation and attention to detail is all that's required. Proper preparation of the system is required for prolonged system and component life.
You've already got a R134a system so there's little to accomplish in that respect. Unless you've had a "catastrophic" failure there's no need to spend the money. I believe you should have a 10PA20 compressor and there are tutorials everywhere.
A good start:
and part 2:
There are different schools of thought regarding oil for the R134a system so substituting PAG for mineral might/should be considered. Further disassembly than the above tutorials is out there and a hot soapy Dawn wash doesn't hurt a thing. Clean all of the clutch plate surface and move on. You'll find other tutorials, these two are just very straight forward to get you orientated!

Bought a 'new" Autozone compressor for my truck and it squealed like a grease pig the minute I started it up. They did compensate me for the gas and oil it wasted.
Rebuilding it yourself is generally no more than seals and if there are published specs for any of the internals, I've never seen them. I would mic the shaft at the seal to make sure there isn't a groove because if there is, it won't seal.
If the compressor seized, you've got to get all of the crap - or potential crap - out of the system or it could ruin your rebuild or new compressor. Even the Discounters warranties say they need some sort of proof that you flushed it and replaced the Accumulator. I'd guess you could take pictures which would probably hold up if you had to go all Judge Judy on them.
