Its very hard to get you a price for any type of work. I will say you have to place your trust in a reputable shop (local or dealership) bear in mind dealerships have bigtime overhead and charge substantially more in labor costs to cover this. And being a local business man I'm partial to them, but its all about trust.
Recommended replacement parts for the timing belt would be: Water pump (a must!), Hoses, if look worn, belts, if cracked, t-stat, a must! I wouldn't wait to much longer for the work. I'm not sure of the maint. Time frame for that vehicle but your gettin' close! Let us know!
