Dedi For A High Quality VPN Provider

I'm about to start a premium VPN service provider, i've found that far too many people in this area are content with providing 100kb/s download speeds and poor reliablity, and think I can provide something better.

I'm currently evaluating options for the hosting i'll need. Initially i'd only be looking at 1 or 2 high bandwidth servers from a quality provider(in the US), on a monthly contract - obviously with the capacity to increase this as and when business becomes a little more established.

I've looked at 10tb.com, and a few uncapped 100Mb providers (Sharktech and others). Obviously I can see the 10tb cap on a gigabit port being a potentially expensive issue - how do they measure this bandwidth? I've noticed that several companies are now only counting the upload which would help me alot, is this standard? Additionally, and considering that i'm specifically NOT going to permit p2p usage in my TOS, would I be correct in assuming that providers will have no issue with this form of service over their network?

Finally, to the more experienced folk here, who would you choose... and why?! Given that i'm marketing this as a premium service, cost isn't the most important factor, but obviously it is one of the considerations.
