Vizag Business owner - advice for selling my family business

Hi all, My family together have been running a small business for a few years. It has become very profitable for the last couple of years. But, we are planning to sell it because we are planning to retire our parents due to their age and health. Any tips and advice is welcome on how I can value our business and sell it to good prospects. Background- Family of 4. 2 brothers. We are earning well enough. Planning to give retirement to our parents. Business background- Food business. Location is near Gajuwaka. Running for last 8 years. Started making decent profits after 2 years of establishment. Last couple of years has seen a very good growth and profits have increased a lot. But it is a very labour intensive job which is done by parents so it is difficult to continue for us. Revenue is approx 2L/month. We have the necessary license but have not registered our business as an entity and do not have Business PAN and GST registration as well. Cannot give more details due to privacy reasons. Can share more details when I know its legit and professional advice with whom I am interacting with on DM.
