Rand,

I would be interested in learning more about your company. In November '06
I started my own company in St. Louis, MO, and it seems that our interests
are very similar. Just to get the name of my company out there, I have
created a monitoring plan for a volunteer water monitoring group who is
interested in the impacts of an upcoming major interstate reconstruction on
a small urban stream.
