Shall I take it that you use your own set-up for this?

I managed to do a bit of guro on a commercial site, but they tightened up their content filters so that I can't get away with that any more.

If there is a commercial service that's this open to guro, I'd love to know what it is.

If not, I'd love to know what kind of hardware it takes to do kind of work yourself, and/or how much patience you have to have with slow rendering times.

From the research I've done so far I'd need a US $5000 GPU to come even close to the per-iteration turn around time I'm getting from a commercial web site.
