I have good web security experience, but no experience in ethical hacking. I have some websites I think they might have vulnerabilities (maybe even SQL injection) but I did not check because it is illegal. I wrote mails to the companies asking for permission to perform a check but didn't get a single reply. I even called one of them but as soon as I mentioned the word website, I heard "no thanks" and the person hung up. This is really frustrating. I want to help people and because of all those scammers around calling random people nobody trusts me. I can understand very well why people like to hack and destroy websites, to be honest, they deserve it.
What the hack should I do to get a company accept my help?!?
