I need a Coder

I need someone who is familiar with wix (preferably) who is able to grab a users location as they log onto the website, and display their location on a map like Google maps (activity updating location preferably) for a food delivery business. Deliveries are done over water and my drivers need to get the most accurate position of their customers as possible.
I don’t need a website designer, or creator, (or maybe I do) I just need someone to help me with this user location setback I’m facing.
