Yo, Just looking for some suggestions. What are other things to offer for sale besides adopts , ych and comms. ? Do bases, cloth and weapons design sell well ?

Custom characters / character design I was always interested in, particularly when it's an artist whose designs I already like. Sketch sheets are something I love but never see offered, and generally have to custom negotiate to get. I'm not the target audience for bases so can't speak to those, clothing and weapon designs though I've enjoyed when they're custom made for a character or prompt, less interested personally in generic examples unless it tickles my fancy just right.
