I think this would be the key ingredient of your pricing strategy. First of all you have to figure out who is your customer and can you rip the most premium by reselling hosting service to them. If you run a "local" shop, most local clients would not be big accounts, they would use less resources than most resource-demanding kids that host media sites, and they will also be ready to spend more.

Then there is professional markets such as design studios that will pay the premium as well.

However, if you targer average hosting customers, these ones do a lot of research and as a rule of thumb would go with a company that offers the most resources for least dollars.

Best,
