I'm looking for a late twenties/thirtyish man with red hair - shorter, no facial hair. (Canon describes it as flame red but I realize that's probably not going to be doable, so "kind of red but not super red" would be fine with me.) I tried looking at who people on IJ use for Weasleys but I haven't had much luck with that, alas.

There's a whopping one canon image I have to work with, so fwiw, it'd be for this guy:
