In the exact same niche, to give you a rough idea of how much traffic you need these are the stats for a fresh site I started on November the first to the 30th (today):
Clicks: 4,214
earnings: $151.72
unique visitors: 14270
Quick bit of maths:
14270/30 (days) = 475 unique visitors a day
$151.72/30(days)= $5.05 a day
Obviously this isn't guranteed it's just a avg, some days I earn $1 if that, others could be $12+
Unfortunatly the cpa network I'm useing doesn't have a very friendly interface so I can't tell you how many clicks converted or the imps without going threw 10 pages.. Youtube bro, drives insane traffic and if you know SEO for Youtube then you can rank for most films, do some major keyword research aswell, I've fount some nice keywords with 26,000 searches and only 2,000 vids if that..
