I have thought of a way to get people to sign up for insurance offers, but it sounds kind of illegal to me. let me know what you think: you leave a note on someone's car, saying "sorry I damaged your car. call me 555-555-5555 or email me at email@example.com" if they call, you will have a voice thing saying "sorry I am not available now, if this is urgent, I would suggest that you email me at firstname.lastname@example.org, I check my email all the time" if they email, you will auto reply "sorry, about that, it was totally my fault. go to this link, answer the questions, and you will be given my insurance info" does this sound like something that could get you in trouble? this is the US we are talking about.
