Halchka99, what type of business is this line needed for just out of curiousity. Is it a possibility that a 60mbit line is a bit overkill?
Most of the time you will spend anywhere between 75-100$ per mbit every month.
You are going to need a serious provider and setup costs will be expensive. You will also need to consider the costs of routers etc. The cheapest bandwidth provider I know of is Cogent Co.
You can check their web site to see which areas they provide service in and talk to a rep on the phone about setup costs etc.
I know they have 100mbit services starting around $4 grand per month (not sure of exact price).
