I wouldn't call it an Ultimate package with only 2gb xfer a month, and is that 600mb per account, or that your allowed? I seriously doubt you'd be able to offer hosting for the next 50 years, and since you don't have TOS posted, you could be found liable for any loss of revenue if something happens, you get into a reck and can't afford the service anymore. So it would be in your best intrest not to offer a plan like that....
