since this is a game jam, no one should expect to pay for anything. this is not a place to find or advertise for commercial work. i will quote Polyducks addressing this also on the discord server:
All participation in the jam should be free and voluntary. If doing more work is outside of the scope for your time for the jam then leave it out. We don’t want this turning into a commercial space where teams are hired. This is a low-effort jam for fun and portfolios.
