Testing the Waters: Reseller Accounts

I've purposely tried to keep my company's hosting business small: I'm the only person around to interact with customers (even though there are technicians at my datacenter who monitor the server and occasionally work on it), but I've tinkered with the idea of offering reseller accounts. Primarily, I envision offering 1 GB to 5 GB of storage space that the individual reseller would be free to divvy up as he or she pleased. You could give away accounts, charge whatever price you liked, etc.

Imagine some theoretical plans, such as:

• 1 GB of space/30 GB of transfers.
• 2 GB of space/60 GB of transfers.
• 3 GB of space/90 GB of transfers.

Plus the following standard features: weekly off server backups, Web Host Manager access so that the reseller can create custom hosting plans to subdivide the space and manage those plans, CPanel access for each sub account, etc. Essentially, this would be very much like a VPS, except that it wouldn't have its own root; because of the way WHM is setup, you would get access to many of the tools I have access to however.

What if I left the transfers as noted above, but doubled the disk space on each of those accounts? Then how much would it be worth?

Any thoughts on what such a service might be worth? Anyone actually interested in such a service (no pressure, just curious if I'm thinking about marketing something no one would want). I'd probably want to sell no more than five of these types of accounts, because one of my primary goals is to insure that the server is not oversold (most hosts sell more service than they can provide, based on the fact that almost no one fully utilizes their account; however, I'm not interested in doing that).

Thanks for letting me pick your collective brains.
