Startup Idea: GPS-Based Hazard Marking for Home Restoration

Startup idea to develop a GPS-based software solution for home restoration workers to mark and track potentially hazardous materials on work sites to prevent injuries.

I work in home restoration.

Sometimes there are dangerous materials on the job. In a burned down house it would be useful if I had a way to mark them so my co-workers do not injure themself. It would be easy to use something like GPS to mark them down.

I would pay $250 a year for this service.
