advice sought on doctoral program

I know it's not in the price range but might look into Swiss Business School, it holds the Swiss Accreditation council (AAQ) also member of AACSB amd ACBSP. And it is probably why their DBA's cost 40k €, there are other options like executive DBA.

You might also have as an option to look into UK online accredited business school, might even see public one's and the prices might go down.
