How to work after 60

Friends

Iam 48 and in an MNC with IT stream. Was wondering if i can do something in Accounting which can fetch me some good work after 55 . Iam a graduate in Industrial Engineering.

CA is purely financial whereas ICWA is somewhat near to Industrial engg. But not sure about how this can be used - in the sense that after retirement i may not be employed so can i start my own practice ? 

There are other qualifications like ACCA etc ....have no inclinations to study hard ones now. Would like to concentrate or work as contractor or start own practice.

I think after 60 no one will get employed on regular rolls.

Your thoughts are appreciated.

Thank you

Regards
