I'll be very interested in responses to this, if any. Back when I last did contract work, $85/hour was the minimum I would take -- and would quote above that depending on location, length of contract, and whether I actually wanted the work in the first place.
And that was in line with several other senior CFML devs I knew rates for back then. I don't know if stuff like Upwork etc has "poisoned the well" in terms of rates these days -- and whether the shrinking pool of good CF devs has affected rates.
