WP Plugin Customization Expert Needed

I need a skilled WordPress developer to customize a plugin. The customization is required on frontend display and backend settings. Write 'olugin' in the header of your bid if you have read this job description. The plugin is for showing locations on map, the plugin shows Regions but it does not show sub-regions. This is what it needs to be worked on. The sub-region should be listed under the Region when it's marked as so.
