GOOGLE You should hit the market where it would effect the market the most. Launch in Miami, Florida. Their prices are extremely high. Look at the Comcast Business Plans $349 a month for 100Mbps. You could blast that market out of the water!
Also Comcast and AT&T have caps. If you can penetrate a large market like that you will be set.
Business != Residential. It's a completely different market. Google hasn't even released business plans yet.
