I think the key factor is starting a hosting business, People tend to buy dedicated servers ob there fiest months. I think that is totally pointless and are loosing great money. I think you should start with a good reliable reseller or vps if you want to offer reseller accounts. And stick with that for at least the first 6 months. And then when you have enough customers (30) buy a dedicated server. Thats the most frequent error in starting a web hosting business.
