Buy a compressor in a way that is being suggested above. And then take it to a mom n pop shop for a vacuum and charge (possibly the shop you already used). Or find a friend who knows how to vacuum and charge properly. Save a good bit of money.
Your car will be much more valuable with a functioning A/C. And you will be less likely to get frustrated with your car.
