It seems strange that the compressor would be locked and the compressor clutch would also be seized. Have you tried starting the truck with the A/C switch turned off?
If the problem is indeed the compressor/clutch and there is no other damage, like debris in the condenser from the compressor being broken up inside, it's a pretty easy swap. You'll need to change the compressor and clutch as an assembly, accumulator/drier, and orifice tube. You'll need some PAG refrigeration oil to lube the o-rings when you put it back together, refrigerant, gauges, and a vacuum pump. Assuming you can borrow the pump and gauges from somebody, you're probably looking at $400-500 worth of parts depending on what you can get the compressor for. If the condenser is full of garbage, then figure another few hours to flush it out. Make sure you flush the high pressure line leading from the compressor to the condenser and the liquid line from the condenser to the orifice tube too. They sell the flush fluid at any auto parts store. You just pour it in and blow it through with air. If it's really bad, you might need to change the condenser. That's as far as the damage is likely to go, though. The orifice tube has a screen in it and will catch the garbage before it hurts the evaporator or lines leading from it. When you remove the orifice tube, check it for chunks of metal or metal shavings. That will give you a pretty good idea if you have garbage in the condenser too.
Once you get everything changed, you need to evacuate the system to a 30" vacuum for at least a couple hours and then charge it.
It's not that tough, but you might want to see if you have any buddies with HVAC experience. It will be a lot easier then.
