Need a flooring cost calculator

Hi,

I want to insert a floor cost calculator on this page

http://contractorquotes.us/hardwood-floor-installation-cost/

and other flooring installation/repair pages on my site, so my users can get an estimate before they get the quotes.

Obviously the calculator needs to be able to be modified. I need different variables like the kind of flooring (hardwood, bamboo, vinyl, laminate etc), the size of the floor, the region etc. How do I do this? I am using Wordpress if this helps.

Hi,
I am professional developer and can develop Javascript based calculator. This calculator would have an admin section to add variables like hardwood etc and price for each variable. You can edit and delete variables from admin section whenever required.

On front end when a user will select a variable, calculator will show live calculation without refreshing that page. I developed a simple calculator and you can see at http://resultatpartner.no/custom-package/. If you click on any checkbox, calculator will show its price.

This is a simple one but you need more flexible and dynamic system. This site is also wp based.

Please send me further details about calculator at kashif @ webcrest.net
