Looking to found a new Cloud Mining Service and hashers store

Hello Fellow Bitcoiners,

I've been following and gathering as much information on altcoins as I can get for the past 4 months or so. Now I want to start up a new Cloud Mining Service / hashers store for the Latin American community and would really appreciate any input on the best way to go.

For the cloud mining service, I'm thinking on starting with 3Gh/s and 10 GH/s packages This is just to get my market's feet wet. Would 1.2 or 2.4Th/s be enough? With this capacity, should I go solo or join the rig into a mining pool, and if, so which one? Could I start just by reselling cex.io services? This would give me a very modest profit margin but It would be a very safe way to invest.

I would also like to mine on script based altcoin protocols, but for me it's way easier to understand about FPGAs or ASICS as they only do one thing: hash. And for the price, they seem to do a good job at it. On the script side of the altcoins I don't yet understand how I could fix a mining rig because they seem to work on the CPUs or GPUs and (I think this) would increase the cost by buying whole computers just to mine. (Am I wrong here?).

On the other hand, about the hashers store, prices seem to have skyrocket in the last month and I need reliable, down to earth costs to do it. Do you think I should buy the chips by the reel and fetch some gerber files to have a batch of hashers made? I've seen in the forums some erupters plans and I could just have them branded? (All intellectual credits given, of course).

Well, that's it. These issues have kept me sleepless for the past few months and now this is my "Newbie" post and I hope I can get friendly advice. I thank all in advance who take the time to answer.
