generally speaking….in my experience, if I needed something specific…I usually end up having to pay for itor spend insane amounts of time looking for it.
Perhaps usingstill images of what you described wouldbe best. All the things you listed seem to be static shots without movement except the firesidechat stuff. Using stillsfor backgrounds is a very common technique and the results can be very professional and can look better than using video backgrounds. If you can’t find any for free, http://www.fotolia.comand http://www.istockphoto.comhave thousands of pictures of almost anything for $1.
Good Luck!
I’ll let you know if I find anything….
