Angie's list DOES charge contractors to be on the top of the list. Sort of like Google, most people don't go past the first 3 or 4. 2 or more great reviews and they will call you if you have a contractor account with them. They will give you a price to be "featured". Depends on the market. In my market with 2 cities that I service, they want 2400 a year.
By the time you can make ends meet....They move the ends.
