I'd recommend doing this job yourself too. It'll be unfamiliar loosening the alternator, steering pump, and ac so that you can get all their belts off, but not hard.

The faq will tell you this: the counter-hold tool (from ipd) for the crank shaft is worth it for this job. Makes loosening and torquing that bolt much easier.

Take this with a grain of salt (noob speaking): you can loosen the camshaft and intermediate shaft bolts if the timing belt is on using the counter-hold tool on the crankshaft. The t-belt keeps them from turning (duh). But when I went to tighten those 2 bolts, the belt would slip. I used a plastic tool with rubber loop that goes around something like an oil filter. With an assistant torquing and me holding we could tighten it. The reason for this may be the newer style t-belts that are circular teeth instead of square. If you do the job without the counter-hold the plastic tool with rubber loop is probably required. I've done the job with and without the counter-hold and it's worth the $35 or whatever.

[EDIT] And buy yourself some white-out to marking where stuff is before you remove the belt.
