When you see the words "easy money" as in OP title just stop and think about it for a minute.
Indeed = no revenue indeed, in my case, for 2 great looking sites, major effort and more than 1M UV's, all in 3 month period.
WTF? Better off with adwords/clickbank ffs. It's probably a good niche but not done that way. We now make more money creating quality and proper unique sites.
Remember, google wants unique content, just scraping sh*t off the pavement and rehashing /republishing won't cut it these days.
