Charity & Social community help website

Hi, I am looking for working with dedicated programmer to develop a site that would be used to help people in local community for charity and social work. People would register and help each other in particular community and as we register skills here they would use the real life skills which are needed in social life like blood donation, charity event, yoga etc and would have feedback and rating system. This is my personal dream and want to help people on social cause in a society. Most of the ideas revolve around computer related freelance but small social workers are neglected. this to bring the gap which internet and facebook has created to ensure people look at internet in a way that helps people build relations. The website would rely on ads through google adsense or advertisement products. Person should have good knowledge of using these tools and seo to ensure website can self sustain its cost. Thanks and regards
