Like say for example I wanted a cool icon for my kbin/lemmy community.
I used the Reddit forhire sub in the past but it seems less active nowadays… plus it’s Reddit…
And I’ve used fiverr before but it seems better suited for having a cool artwork made than for webdesign or something highly specific due to the language barrier.
Designer here. You could try searching for communities on the fediverse dedicated to design/web design/3D/etc and contacting someone if you like their work or just making a post about it if allowed, or a mastodon/microblog post with lots of related hashtags. Or if you really wanna widen the net, you can try looking on Twitter/Threads/Dribbble/etc. for people you like and contacting them.
