Economic depression and holding a scientific meeting

The current global economic depression is also affecting budget situation of holding a scientific meeting. I will chair a domestic symposium on the complement system in Aug 2009, and now trying to collect funding from several companies related to the complement research and to my laboratory. Currently, the trials have been in vein. They have very good or crying excuse about the toughness of the economic situation in these years. The worse is that I have failed to get a good research grant in this year, so they do not expect a good order or purchase from me, perhaps as a real reason. But if someone offer a good donation especially under such condition this year, I will treat such dealer/company with much better privilege upon my grant success next year ^^;
