I need a Word Press developer

We have recently had a new website designed in Word Press. We were hoping to have an interactive map showing all of the countries we have worked in but unfortunately the developer wasn't able to achieve this. Instead we currently have a static map with pins showing the countries we have worked in. We want to change the map so that when each pin it clicked/hovered over it brings up the name of the country and icons to show the work we have carried out (we have the icons).
