You have all of the symptons of a leaking air conditioning system. Look on the list of things the mechanic did, and see if one of the items is a leak check of the system. If so, what kind of warrenty did he offer? I would first take it back to him and see if he will make good on any promises he may have made. If he suspected leaks, he should have put some dye in the system. Now he should be able to look and see where the leak is, and hopefully it will be something easy.
I have to warn you, that if that is the original compressor, it may be ready to be changed. They usually will run around $500 or more to replace, and the accumulator and orifice tube will have to be replaced also.
If by some chance it is not leaking, then he should be able to fix your problem. I know this is costing a lot of money, and if your climate is where you can do without a/c, then just run the air on vent with the windows down. If you can make it another month, things will start to cool down, and give yourself all winter to save some cash for repairs.
