I'm considering doing icon commissions, using some templates that I am currently in the process of creating. If I manage to bring up my confidence enough and can get them ready, I may open up the service. The icons/graphics will be animal or furry related. If I can work on my art enough and can improve on my people, I will try to include them as well. The prices will probably be $3-5 a piece, with the possibility of buying in bulk/batches, but I'm not positive on that.
My intention is to sell them through FA, DA, and possibly here.
