Help with establishing a small scale industry - Neem based Products

Hi All

We have over 2000 neem trees in our farms located in Tuticorin district , tamil Nadu. We can also procure from others if more quantity is required.  I am exploring the possibilities to establish a small scale industry to extract Neem oil, produce Neem cake, Neem based pesticide etc…

Does anyone in the forum have experience with the same. If so can some of you throw some light on the same.

looking forward to your inputs
