If you don't want to change your career, IMD is a good choice. Be careful, you may need your wife or girlfriend to "onsite" support your study in Switzerland. Otherwise, I doubt whether you have time or energy to feed yourself everyday
yalemba, pls check IMD's deadlines as below or find more info. on its website. But its admission officer told that you need to be interviewed in Lausanne if you miss the deadline of Apr. 1.
