Anything Goes : How do I find sponsors? by Larry Ross

I do interviews on my you tube channel named Pay it Forward TV and need some supplies to do a better job with my videos. How do I go about finding somebody to get a lap top and a good professional video editor program in exchange for saying Pay it Forward TV is sponsored by (...)? I could also use printed stuff as press passes for myself and my camera person, t shirts, biz cards, logos for my car doors and a back drop logo and a better video camera a like. But I just love interviewing people about helping out in our community and don't know anything about how to find sponsors for my own show. Any suggestions?
