Immigration dept permission for taking employment

Sir
I am married to malaysian woman and have LTSVP stamped first for 6 months and again now renewed for one year...i am 65 years young indian..how to get immigration permission to work in my wife's company as Business consultant ..not for salary but to get share in the profit made by the company at the end of every financial year...which means company needs to pay me for my consultancy if it makes profit bcos of my consultancy..

To do that you would need to set up your own company to offer consultancy services.
