I am an MBA in marketing. What would be the ideal business for me? Actually I can't invest much money, give me the answer please.

This question is asked a lot, and there is no answer. It depends where you live and what your areas of interest and expertise are (even with an MBA). Having limited funds means very limited choices too. Consulting is a typical answer, but that requires experience. Maybe you can consult for small entrepreneurs who have an idea or product or craft, but no idea how to deal with the government.

If it was really that simple, don't you think we all would be doing it?
