Waterpumps do fail, fact of life. A '99 means the pump is now 8-9 years old. At that age, it's not unusual regardless of mileage to have it fail.

It's a pretty easy DIY. I personally would not pay to have it done. The pump runs about $300 (cheaper on eBay), not sure if there's a rebuild kit for one, but if so, this is also an option. A rebuild consists of replacing everything but the actual casting. Seal, Bearing, Shaft, Impeller are all new. Usually the shaft needs to be pressed out and the new pressed in - I've had NAPA machine shops do this work for me in the past for under $50 with good results. You'd also need a new gasket - $8 which has to be cut because it is also the gasket for the Oil pump - an easy modification. Then you'd need 2 gal. of coolant and 2 gal. of distilled water - say $30 max. If I were going to that trouble, on a '99, I'd also change out the 'T'stat - another $15 incl. gasket.
