A year ago a "friend" of me hired a russian hacker, just for a joke, and he hacked my gmail, twitter and facebook accounts. And the passwords were random 10 caracters or something like that. He hired the hacker in free-lance.ru
I'm sorry but I don't know how did he do it. I was wondered when I saw that I can't login in to my gmail account. I thought that it's impossible someone to hack my gmail account, because Google is a big company they should have some good codes there. But it's possible. In that day my friend sent my new password per sms my and said that it was a joke.
if you want to hire someone, go to free-lance.ru, in left menu select web-programmin (Веб-программирование)then secyrity (Защита информации) and hire someone. Some of them will do the work, if not, they know someone who can do it.

If you couldn't log in, he did it by guessing the answers to your security questions based on other stuff he could find out about you online, and resetting your password (possibly resetting or taking control of your backup email account that you had your new password set to send to, you should check all that stuff).
You're seriously wondering whether or not someone is going to trust their secrets and the source of their income with a complete stranger, and further pondering whether or not you can trust an anonymous criminal?
