Hi Scotty,
Rockauto.com sells an Aisin water pump for that engine for under $90. Not sure how much labor is involved but it appears to be not too terrible and is potentially a DIY job:

WalMart shows a set of 4 Goodyear tires your size at $532, though you have to add taxes, mounting, and balancing:

The point is that if the vehicle is otherwise in good shape and considering the cost of replacing it, perhaps you should do some more shopping around for what it currently needs.
@chucktobias Hi Chuck, Thank you for your help. Thank you for your research. I think you are correct. I did find out that because my Venza is a 6 cylinder and not a 4 cylinder the labor is higher since the parts are close together and there is not a lot of room. Most of the water pump replacement is in the labor cost. It looks like I can get a great deal on tires and pay around $700.00. My driveway is very steep and in the winter it is tough to get up.
I am Researching all weather tires so I do not need 2 sets of tires. They are a little more money but worth it.
