Is there a business idea here?

I emailed 6 block wall companies for some work I need done, and I got one reply.

The other 5 didn't even have an auto responder...nothing.

I assume these business owners don't mean to purposely ignore a potential new customer, but they did.

Is there something we can offer them and make money?

A thought I had...put them on a website for unresponsive businesses...let them know they are on it...give them options to get off. This sounds a bit like blackmail, which isn't my purpose.

Just trying to think outside the box...curious if anyone has an interest in this one?

Thanks,

WW
