Bottom line, the more you save, the more sites and link campaigns you can run. The more campaigns + reinvest = even more sites. Spiral until you can skim enough (30% or so) to live on and continue reinvesting.
The less money, the less sites. You'll be a success if you know what you are doing, however, the good money will come years down the line if you only have a few bucks to start with.
