Custom Openstreetmaps/leaflet.JS Development

Customize WordPress site which uses leaflet.js for map. I need to add a feature that allows users to draw polygons on the map, and add fields to the database to store, display, and edit this polygon data.

Note: (leaflet.js has support for this feature built-in)

please let me know if this is something you feel you can accomplish, so I can give you more details.
