We will share Tamil Nadu NGO Brands working on this issue.
These are NGOs financially supported by corporates, corporate foundations, funding agencies, philanthropists.

Donor and volunteers can see their website, about the NGO, who started it, governance policies, financials, who is supporting them, districts where they work and take a decision to support them. Ideally, we dont want you to communicate with us because after studying who is supporting them, we have arrived at the decision. We also dont want any commission for the amount of money you give the NGO Brand because that money, you can invest in the NGO. You or journalists who write about the NGO, need not take any permission from us and it is not required to mention us for publicity. We want the NGO to get more publicity and act as guardians or non biological parents of the NGO (we may not know or visit the NGO)

If you are supporting an NGO, which is not covered by us in this state, do share the NGO Brand name & website link, and we will share the NGO.
The only advice we get and therefore forward to you is that the NGO should not be started by a politician or political parties because in India, we will enter into legal zone where someone may question us that we have shared the NGO because of political goodwill or pressure.
