Disesh,
Will you dedicate 100% of your time or part time?
Why can’t you try with retail shop of agri produce along with processed food items together?
If you have plenty of coconut leafs, then start making of coconut broom stick & other allied activities depending on agriculture produce.
You cannot survive single value added product only from Coconut.
If you open retail shop, coconut can be sold as tender coconut, copra, matured coconut along with other business.
why dont you investigate the possibility of producing soil less media using coconut waste, there seems to be good demand for this e.g. google coir grow bags, media etc
