not sure if you need a reseller account, you need the reseller space - but whatever. Most descent hosts should be able to provide what you need with a customized or a standard package, talk to some of the sales people at places that interest you, I am sure you will find someone, good luck. Also at that size, depending on the bandwidth you would be using, I would expect to pay between 30.00 to 50.00 per month or 279.00 - 500.00 per year. Figures are based on if you actually used that space, be careful of those that offer the world for cheap, read the fine print closely. Good luck in your venture.
