How to assess demand for traveling RNs?

[Cheng Chu]

I'm just curious how other people get started with MTRs?  I live in a medium sized city with multiple hospitals and I do see a lot of traveling RNs.  I go to furnished finder and I see couple of of listings, but quality of pictures are bad, and I have no idea how full their calendars are.  Does anyone have a process they go through to check demand for traveling medical professionals?
