Duke, whiy don't you go slowly slowly and do it via reselling first, then maybe you can make some money along the way and test out some ideas..that's what I'm doing. I had a serious disagreement or two with my hosting company here in Spain about some really simple customer service and tech things, stormed off in a huff around the internet and discovered reselling and a company called Rochen in the UK (

It's a really good set-up and, now I have got a couple of other projects going, my next one is to set up a niche hosting site for bloggers and online-communities. From the clients point of view, they don't know if you have a reseller account or three whole datacenters tucked up your sleeve (as long as you don't tell 'em)
