59374 web page creator

i need a simple html page creator. i want to use a basic template for some webpages i need created. i want the script to make as many pages as I want using them template, but chaning some word variables for instance, there is a webpage with the word FORD in it several times. I would want the ability to make many pages but change FORD to CHEVY, and AUDI and MERCEDES etc.. so i need the script to be able to get a list of keywords that i want the in the web pages, and the template would have to have some identifier so the words i choose can be added there. i actually need it to make over 12000 city specific pages - with only the city names changing on the built web pages.
