I need a professional website to display live map updates +.. See description..

General information for the website: Displays DVSA / VOSA vehicle checkpoint activity and hotspots
Description of every page/module: Live map showing hotspots and checkpoint status
Forum
Description of requirements/features: Advertising space
Extra notes: I have a Facebook page where people can update each other on which DVSA / VOSA road checkpoints are currently open or where a roadside checkpoint is operating. (see www.facebook.com/SpottedVosa )
I would like a website to show this info on a live map. (with journey routing options to show if your route or location is near a "hotspot")
Members should be able to update the map locations from the website and then locations to be automatically posted to facebook page. (and vice versa if possible)
Note: Many of the checkpoint sites are mobile so members should be able to enter new locations.
Website should also contain advertising space and a forum or link to forum for topical chat.
Please get in touch if you think you can help with this project.
