Ok, they get 200 MB of disk space....but 99% of them don`t even use 5 MB and not one site uses more than 1 gig bandwidth per month.
The package specs like disk space/bandwidth could easily be lowered without ticking customers off, that`s no biggy.
The few bitchy ones who would complain...just let them keep their bigger package as is.
i would suspect you can get somewhere between 3k to 40k depending on a lot of factors.
-are the customers annual or monthly
-do they pay by credit card or some other means
-do you have financial statments to back up your sales claims
those sorts of questions would help to determine the actual value.
