Develop awesome interactive map of our employee locations

We are looking for a developer with a good eye for design to create an interactive map of all our employee locations (country level) using employees photos as the map marker. The map should be in our corporate design and we should be able to embed it in our website, in Confluence and in presentations. We have seen similar maps we like that were created using Mapbox but are open to your recommendations with regard to the technology. We should be able to easily update the map (add and remove locations & photos) ourselves after it has been created. Scope: Creation of interactive & editable map in our CI with employee photos shown at each of their locations.
