Calculator Script

The project we have would be very simple for an experienced coder. We have no preference as to the exact language the script is written in, though we are partial to java and php. The script will actually be an estimator script. We own a cleaning service, and the customer would select from a handful of variables to arrive at a cleaning estimate. My preference is of course that it be easy to use, and the variables easy to change according to inflation, etc. I'm open to all suggestions, bearing in mind that I will need to be able to use the script on several different pages of our site, with each page dealing with a different service.

As I said this could be a fairly simple task for one with experience. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition. 3) We become the owners of the code, with the ability to use it as often as we wish, wherever we want. ## Platform Should be able to be inserted as a form into our webpages. Can either be javascript, or php driven. Easy modification of variable prices, etc. Our webservers are Linux
