I am referring that I am going to offer a location where you can send the machines, were it will have a temp controlled room... and I will only charge 25usd per month for each machine that you sent me. It will include included everything so that the machines work in perfect conditions so that you has a client dont bother on always being checking on the machines and getting a better profit per month on your investment.
So, it is co-location hosting that you are talking about... In order to send server to your data center, I believe your reputation must be great. And cost of shipping server computer to another country is expensive and risky.
I would suggest you get some computers and rent out, it is much practical...
