Very broad range depending on experience and responsibilities. If all you are doing is just one aspect of the process I would not expect much. I have seen shippers (brokers) here (Oak Ridge) that act essentially as the Project Manager and handle the entire gamut of personnel management, characterization, waste profiles for the landfill, packaging, and shipment. Then there are those that get a package already to go fill out the shipping papers and watch the truck (or train) leave. I have worked here as a Waste Specialist and made more than many of the project managers in the company, then there are those who just watch boxes being filled and make entry level pay. Don't get to hung up on the titles, if you are working here as a contractor pay will follow responsibilities. I have shipped hundreds of thousands of cubic feet of waste from remediation's and demolitions and I do not consider myself a shipper, if you do not do it full time all year it is difficult to keep up with the regs. A six month lull from shipping is enough to make me feel like I am starting all over again.
Do some networking, figure out where you are in the "Food Chain" and go from there.
