Hi Passionately.
Why dont you set up your own business? What sort of line are you in...is it the sort of thing that you need a business partner for?
Your local Bank manager is likely to be part of a business networking group so perhaps they could recommend you to a group.
In the meantime if you just need an income I would suggest dropping the MD title from your CV or at least say that you want a career change as this would certainly put me off if I was interviewing you, it gives the impression that you are indeed to big for the role and may leave as soon as something better comes along! Could you not change your title to Manager just so you can get a foot in the door?
Best of Luck
