To answer my own question... after a bit of research, I'm seeing 10% on the low end to 100% on the "grab the money and run" end. Jeesh.
Location is going to be a major factor. Sometimes more than experience or credentials*.
New Yorkers ask a lot of money for everything. Of course it's a generalization that will not apply to all, but the majority would like a lot of money. So a producer from NYC may ask 2x-3x more than others for the type of remote producer work discussed here.
I know because I've been told I'm too expensive. (Haven't we all?)
I'm sure expensive people exist everywhere (and of course some can ask for anything because of their status).
