Search feature for MyMaps

Hi there, I run a website called PuppyGoGo.com. We use CB for our user management system. I was wondering, have you a product that enables a visitor to the site to search for members using their geolocation as listed in CB (I wasn't sure MyMaps could do this)? For instance, all members are displayed on a map.
If not, is there a custom build option that you provide?
Look forward to hearing from you.
Kind regards
Shaun
