But i can't decide what price i should sell it at. Any suggestions?
1. If you're saying you're getting unmetered "bandwidth" with that reseller account, I'd be a bit weary about it. For one, there is a limit to how much data that server can push, second, all the resellers will try to take advantage of the basically "no limit" data transfer, and beef up their offers with huge transfer allocations. In turn, the server has good chances to get too busy, especially in the long run.
2. Figure out your costs and come up with a rough cost/space unit. Price the packages around that (of course, not forgetting a markup). Without knowing your costs, your taget market etc, no one can tell what a good price would be.
3. If you're actually the owner of a server and trying to market a reseller package with the specs that you've described, see #1.
This is just my opinion, but it sounds like maybe you should do a little more research in the hosting industry before you take this public and start taking on customers.
The thing that worries me is if you are having problems just setting prices what is your level of knowledge for all the other aspects or running a web hosting company. Running a decent hosting company takes alot of research, time and effort, knowledge of the industry, and many other factors not mentioned.
