> How difficult was it to get on Steam and other vendors?

Not difficult at all. Pay the fee, get something going.

> Are there any artists you'd recommend working with? I need a 3D/Blender artist, especially.

My e-mail is on my profile, happy to send a few intros your way.

Steam is simple - pay the $99 and follow the instructions.

Depending on the kind of artist you want I might be able to recommend some people, have you done this before?

I'm saying this as a gamedev who's had some mixed experiences, not an expert at this at all, so happy to pass on any useful tips if it's helpful
