Hi folks, good morning.

I know people that would like to work as a Keyworder/Keymaster. So I wonder if you guys know:

1) Where to find Crowd-work (crowd-sourcing, crowd-whatever) sites where these friends can apply to work as keworder/keymaster;
2) If you're a Photographer that would like to hire them, how much are you willing to pay per image (keyword/tittle/description) and what is your needed workflow;
3) Any other tip is welcome regarding keyword/keymaster hiring.

Thanks in advance
