You asked about number of pageviews - number of unique visitors is more relevant.
I would say reaching 1 million uniques a month could be considered fairly big for a one person operation. If this is about how much money you'll be making it really depends on what type of website you have. Some verticals will make you more than enough with much less traffic.
