Hello Padmaja,
Corporate Social Responsibility is a vast area. Instead of thinking of big expenses, why don't you start from scratch?
1. Since you work in an IT company, you can distribute your old computers to village schools, other NGOs, orphanages, etc. There are lots of poor kids who have not even seen computers at this age.
2. Try to visit some slums or colonies or contact a few NGOs that function based on slums. Find intelligent kids and try to sponsor their education collectively or through the company.
3. Periodically arrange organizational visits to NGOs, poor homes, etc., with your employees so that they will have an idea about the poor class in the society they live in.
4. When the academic year begins, you can find kids and distribute study materials to them.
5. Occasionally visit hospitals where chronic patients are treated. If you find that they are financially marginalized, offer your helping hand to them. Make sure they are indeed poor before you start helping them.
6. Why don't you celebrate your company's anniversary, birthday party, marriage anniversary, etc., in an orphanage?
I think you will get thousands of ideas. I am from Trivandrum, and I don't know the exact situation in Hyderabad.
Thanks,
Afsal
