Just make your own and grow it like you are possessed. If you limit your framework to other people's possibilities, you may actually underachieve. I mean probably 60-70% of people in IM never even make any money at all. It would be unwise to ask the masses.
I have one niche site that makes me $10/day. I have another niche site that makes me $150k/year. It really depends on the niche, the traffic, etc.
