Seriously? What if you will just abused it? And even if you present yourself as a part of the team, it will still be hard to convince us. There is no need for you to test the bugs if they are working or not, because it was not some kind of a feature that needs to be perfect but the more the owners will like the bugs to be killed immediately before it can cause a lot of damage to their websites.

If you want to find bugs you can find it on your own. Now on topic, so many sites are vulnerable in the past but good thing that number has declined as the site creator are more familiar on the technology but they shouldn't be confident since the knowledge of the hackers are also improving.
