You might want to contact Wizdom. He sells blocks of 404 traffic for 100 bucks US for 20,00 uniques. A lot of people get a dump like that to get their CJ going and have had a lot of luck with it.
I don't use CJ so I have never used it myself, but I spoke with him about it on the phone and with others that have used his service. They swear by it to get the initial jumpstart to fuel their CJ's.
Let me know how you make out.
Regards,
