Help me donate to Tamil Nadu children

Last time we were in Madurai we visited an orphanage and we have since sent them money regularly. Although it feels good to help out I can't help feeling like a cash-cow that is milked over and over again. The manager keeps asking for money because of 'this and that'. I have no idea how the money are used and no guarantee that it is spent on the children.

So I am thinking, maybe I should direct my donations through a larger organization that has better control? Where can I find such an organization? We want to support orphan children in Tamil Nadu.

In two weeks time I am also going to Tamil Nadu and will stay in an orphanage in Muttom. I have been given the contact in this orphanage by the Rotary Organisation in Malta. Apparantely Rotary - Malta had collected some $25K (which sum the Rotary International had eventually doubled i.e. $50K)for a school to be built in the area of Tamil Nadu.
What I can tell you is that I have contacted the father who runs the place and he seems to be a very honest man. Right now they are in the process of building a new floor to the school, so they obviously require funds.
You will find all the required info on the website. I will look it up and post it later. The School / Home is called St. Joseph's Children Home in Muttom. It looks like a very good and honest initiative.
