Where to post a FanArt competition for my business?

I only recently started using Reddit for unrelated things. Seems like a good place to find artists that want to submit something they made. Just checking through many art subs, large and small, and finding that contest posts are prohibited. Looking for the best way to reach people that regularly do fan art and would be interested in participating in a new thing for a chance to win some money. Can give more detail as needed. Appreciate any on-site suggestions as I'm familiar and planning on using other sites as well. Thanks!
