First I say you need to get a second opinion. Ask around and find an experienced AC mechanic in the local area. Have them check over the AC unit.
Second get it recharged. If previous owner had system recharged and it worked there is a possibility system is ounce or two short. When system is low over an ounce it shuts down or cycles on and off. So when I recently got my Contour SE recharged it cost $80 bucks..
Now before you get recharge buy the $20 AC kit then hook it up. See if there is pressure then turn on AC. See if system cycles because of low pressure. Try to charge on the low side an ounce or two.. If this works you may have a small leak that requires you to charge yearly.
If system has pressure and the compressor does not start there may be a relay or minor electrical problem. One could take out a blue print and check the wiring or get a professional to inspect.
Now if you go to shop and state what you found you might get a discount. The guy will know that you have a clue, most people dont.
Good luck and check this out since a $200 dollar repair is much nicer then a new $40,000 purchase.

I suspect you tried the recharge already. Sometimes if the system tries to run without oil and freon compressor locks up.. The system typically has a sensor of some sort to prevent operation if low on freon.
Maintenance on any system by a competent technician should be done with solid troubleshooting. Start with the cheepest potential solution and go from there.
Now if one were to put freon into system and monitor pressure they would know quickly if system had a charge. If one were to inspect electrical components and wiring with a volt meter and blue prints they could potentially determine problem or problems.
Reguardless try to find an experienced AC mechanic and make it like you have a clue.. System has pressure... System cycles on and off..
I have heard that replacing the AC compressor has worked for others.

He stated to check out fuses.
Also the clutch coil often goes bad. This engages the AC unit.
Often the compressor is not the issue.. If it does not start there are so many components that support the compressor.
