Need Option to Select Who to Submit Form to Based on GeoLocation

Here’s what I’m trying to accomplish:

Using GF to create a trailer builder tool. Potential customer can select the trailer they wish to customize, use the form to select colors, flooring options, custom lighting kits, etc. When they get to “submit” I want them to be able to see a list of dealers in their area and select which dealer they want to submit their form to for a quote.

We are already using the WP Store Locator plugin to allow people to find a dealer near them so all our dealers’ info is already in that. I would love to be able to integrate that into the form.
