Hi again.
Usually when the timing belt is replaced, the water pump is also replaced, because it usually fails just after you get the belt replaced. This job could be done in the driveway, and there is a how to in the "how to" locker. If you need to find a good source of parts, let me know and I can suggest a few. Burlington is the only place I have had any experience and it is only 25 miles south of Bellingham.
