Buying bulk accounts cheap.

I'm looking to buy bulk accounts cheap, an example of what i want is a very memorable login, or in some sort of order for example:

[email protected]
[email protected]
and so on


I don't care about the display name, i just want short and similar logins. I'm looking to pay around 50k per account, since i'm not really buying anything worth having to most people. Same password is also preferred.

Let me know.
