Well I must admit, while pouring through a few posts it's surprisingly hard to find anything about mining farm hosting locations. Please point me in the right direction if I'm wrong!
You looked in the wrong way. There's a lot of information in this forum and the better way to find anything is (imho) google. In your case a query like mining farm hosting site:bitcointalk.org would do the job.
Maybe you'll do that search to see what other questions and problems others have. For example I am sure that the country is important, there may be a trust issue (what happens if you sell the devices and "go bankrupt"), transport fees and tax and probably many other things...
