Just finished doing my '89 911. Wasn't able to work on it full time, so few hours a day, took about two weeks. Worked alone all but about 10 minutes worth. A helper can be very ... helpful, but you can do most of it by yourself.
Not sure how the system is configured on yours (vis a vis, later cars), but it's plenty tedious at best. If you have a lift, good for you. If you're working under the car on jack stands, it's tougher for sure. In general, the instructions would suggest that you need to be a factory certified Porsche mechanic with air conditioning certification. Any reasonably adept mechanic should be able to handle this just fine. Read directions, take your time, keep track of all the screws, clamps, and hardware, and take lots of pics B4 taking things apart as you go. Most intricate part on mine was the evaporator under the front trunk. Most miserable part is all the hoses. May take a little creativity to get the hoses to bend and stay where you want them while you screw the clamps back down.
Good news on mine: no leaks, all the electrics and controls worked fine. Haven't charged it yet, so can't report on performance yet but don't expect any problems. Good luck.
