I need a simple web-based calculator created, preferably in PHP. It will have a couple fields for the user to complete and then it will produce a single answer. I will provide the formula for the calculation. I want the calculator to look professional and consistent with my site's look and feel. The site is www.limoncelloquest.com. The deliverable needs to be some code that I can copy and paste into a Wordpress page and have it work.
If this is done well and for a reasonable price, I have about a dozen more I need done for another site so there could be future work as well.
