Natalie,
I used to have an old Dodge Dart (rear wheel drive), went skiing by myself all the time and got good at putting on chains. The easiest way is to lay them out flat in the direction of travel in front of the wheels you are putting them on. Have the hooks to the front, inside of chains facing up. Then slowly drive on to them to about a foot from the front edge. Get out and loop the chains over the tires, back to front, hook as necessary and attach the stretchers if they have them. The box you buy them in will have additional instructions if you need it. The only time you have to jack the car up is if you get stuck in a spot you can't drive forward...or backward for that matter. And like Strick said, to get them off, just unhook and drive off them. And you might want to practice in your driveway once.
And in fact, the first time I put them on my new Saab, I stopped in the chainup area, jumped out and got them on the rear tires easy, maybe took ten minutes. Got back in the car, sat for a second, um, oh yeah, this is a front wheel drive car. So after looking around to see who was laughing their heads off, I hopped out, changed them to the front wheels, and was off.
You can do it yourself, no problem. Bring some gloves you don't mind getting dirty.
