I'm told by local operators here I have talked to, that I can be picked up for non-paid, supplemental flying by several outfits around here when I have the COMM and 150+ hours. My CFI did a few jobs for some of them when he was at the same place I was time wise, so for me it's get time, get time, get time.
As it is when I bag the Comm I'll start CFI, hopefully when I have the time built up, I'll then take on some odds and end things to grab more time as I progress. the operators that do this know that we might leave when enought time is gained to pursue other objectives, but it's offset by the continuous stream of other people coming in, like me.
