Looking for a new experience, abroad, my company in my bag: where?

I currently run a small consultancy firm in Switzerland. Business is doing well, almost routinely. But I am bored. I am now considering the idea of moving abroad but I have no idea where to.

Question: do you know any good resource that provides specific information for business owners willing to start abroad? I am looking for some sort of worldwide economic development index ranking, combined with some information on how easy it is move and start a business (VISAs, costs of living, conditions and costs for starting a new company, etc.)

Any ideas?
