I'm working on a website that needs to have a certain function on its form. The form allows visitors to submit data for a quote, and I'd like to have it so that when a start address and a destination address are entered, and the form is submitted (which includes a lot of other fields), the form data will pass through Google Maps and produce the driving distance and driving time between the two addresses, and include these results in the email that has the data from the form submission that gets emailed to the site owner.

The plugin that I'll be using for the form is Formidable Pro, and I was told by the creator of that plugin that the plugin, MapPress could do the job and work nicely with her plugin. I emailed the creator of MapPress a couple of weeks ago, but never heard back from him.

Is this an easy thing to do if I only know HTML, Wordpress, and a little PHP?

If not, how much would it cost for me to pay a programmer to do this?

TIA
