I need to create a web page that incorporates javascript

I have a client that would like a Bookkeeping Pricing Calculator on her site like the one here - http://www.bowiz.com/pricing.html

Not being a javascript person I am seeking help from someone to write the js code for the calculator. I am willing to pay for services but don’t see anywhere to post such a request. Further, I really don’t know how much I should be paying for such a service.

Any advice appreciated.

Your better off searching for a developer in the marketplace or on a freelance website rather then in a public forum.
