How do I get a distance finder?

Hi,

I am trying to simply place a small widget just displaying how far private instructors are away from them so they get ones that are closer. I'll be putting this in a list of the teachers as well as in their profile. Do you have any recommendations for making just this data available in a sidebar or post?

Thank you so much for your time and amazing plug-ins. Keep up the great work!
