Seeking sponsorship

How does one find sponsors for a project like recording the Madai-kara? Well on the basis that people find it easier to give services and materials than cash I've been searching through my contacts this afternoon and asking for help. I want to ensure media coverage so I've been asking folk like fRoots, Songlines, BBC World Service and so on if they would like an article or package. I've also started to scrounge equipment. If we can avoid renting camera's and the other recording gear we need we will save around £1,000. The greatest expense though are the flights. Anybody know anyone at Aeroflot???
