Please get a basic understanding of cracking before asking for something like that.
Combos are email:password combinations you test against a site. The ones that work are called hits and can have capture depending on the software you are using.
So, knowing that, also understand that this isnt a cracking forum and you are much better off learning how to crack by yourself using a couple tutorials (Shouldnt take more than a sentry mba guide on youtube to do the trick).
