Fiverr
- I understand what you mean about the cut! I started using it recently and charge USD while I'm in Canada, so by the time the currency changes I make in CAD about what my prices were (if that makes sense). I kinda look at the cut as payment for the gigs coming to me. I can just leave them up, have the app and forget about it - until a client reaches out to me. So it's less work on the promoting yourself / searching for job end at least.
I'm not really sure what you mean about the digits and the issue there though. But i'll leave this comment here in case someone else is trying to find some places for commissions too ^^
YCH
- Maybe try Your Character Here commissions, I started these recenty and it seems there's a decent market for them on deviantart (which, i know i know - not the best place. But the YCH community doesn't seem half bad. Most from what I see are willing to pay proper prices) with the holidays coming up, I suggest doing quick holiday icons or something that you can use the same base for if you need quick cash.
You can probably try selling these elsewhere, I just see they're more established/known about on deviantart.
