Does anyone know any artists...

[Emperor]

Does anyone know any GOOD artists who'd be willing to take some requests? Most people who are willing to take requests are either very bad at it, or shame me when I request... well, you know what I mean.

i have been probing tumblr and other artsites for this question
(i gave up on deviantart, it's a sewer of stolen art, tracings, and crayon scribbles)
haven't found good answers, except find someone who's into far freakier shit (like straight up guro or something) and who's asking for money for commissions, they might comply. this has worked for me, unfortunately the toilet pic produced wasn't as quality as their other horror stuff because they don't do that regularly.

or learn japanese and go to pixiv, they're far looser on this kind of thing in general

at-sign-drawfriend drew two amazing toilet pics, might be willing to answer requests, generally
if dustindemon's still alive, maybe he'd do commissions,  but i haven't heard from him in forever
mamabliss does commissions, whether that art's acceptable or not or worth the ten years it takes to draw them is up to you
pertheus did those two commissions from yarr (chun-li and faye back-view in bathroom, you know the ones)
pmafterdark. tumblr. com/post/50848547174/and-without-further-ado-you-enter-the-shady (remove spaces) claims to be offering commisions of "any fetish save for Furries and Expansion!" which leaves this kind of thing as a possibility, hopefully they really mean it!

other than that, i have no answer
sigh. the fetish is too tame for the freakier artists and too weird for the normal cheesecake artists.
