Challenge me on Web Application Security???

One day after the application penetration test, i was contacted by an huge organization who apparently view/read my blog. Basically they issue a challenge to test on my knowledge and skills on web application security assessment. Well, i don't really care or bother how huge you organization is, i accept your challenge and i will show you that your public facing website will be used as a zombie for unidentified attacks. Don't blame me for that. You issue a challenge and i responded. I don't have anything to prove, except that i would love to see how good is your web security.
