yes, its sounds exactly like it happened to you.
a note that this is copied from craigslist would have been all that was needed.
Thanks for this post. I will be having a guy here shortly working on my house as well. I'll have to shake him down before they get started!
To be fair to the contractors you should ask them for copies before they come to the house. Most companies that have employees aren't handing out copies to keep in every truck on the road. I know i don't. To check on a company go to sunbiz.org and see if they are registered and up to date. If you are really concerned you can have them list you as additional insured but that will probably cost you an additional $200-300. The problem comes in when you hire an UNLICENSED contractor.
I added a note to the original post about this being from a Craigslist ad. Hope no one minds.
