Web sites & Databases?

I need to be pointed in the right direction…

I’m building a web site for a car suspension business. They need their customers to be able to search though their products by the cars make, model & year.

Only problem is I’ve never made database or even know how to begin to search it.

so are there any:

a) any programs that does this for you

b) any one who wants to make a few bucks on the side

c) any websites that sells the code that allows type of thing to be done

or anything else that would be helpful…
