Looking for a legitimate dropshipping mentor who teaches beginners

I am interested in learning dropshipping, but I am also very cautious because there are so many scams, exaggerated income claims, and people selling expensive courses.

Has anyone here successfully learned dropshipping from a legitimate mentor or community?

I am specifically looking for someone who can teach me the process step by step, including product research, setting up the store, suppliers, advertising, fulfillment, and understanding the actual costs and profit margins.

I am currently looking for work and trying to find a realistic way to generate income. I am not looking for overnight promises or anyone claiming guaranteed results.

Please only recommend people, communities, or programs you have personally used and had a legitimate experience with. I would also appreciate knowing what you paid and whether you made a real profit after advertising and other expenses. Do not DM only respond here.
