I was a high school teacher that wanted to recover Oligocene marine fossils for South Carolina museums. My students and I built a darkroom to sell pictures, we ran every school dance, every concession at every dance, turned out the first yearbooks the school ever had and collected a cut off everything. They helped us build a field station. We did what your talking about in a very small way, but there's no limit to what you can do using business to further your efforts in paleontology.
Business is alot like evolution itself.
I am not that naive. You could look for partnerships also.
