I Bow to Your Knowledge and Connections and Experience

Friends who know and/or are artsy types:

I'm looking for an artist to do some geeky commissions of my fiancé and me. I have no idea where to look. I want to say DeviantArt, but that site is MASSIVE and I would get lost. I'd love some recommendations on artists whose work you love and preferably have interacted with in some way.

I just got burned and strung along for four months and lost a good chunk of change on an artist who didn't deliver so at this point I'm looking for solid character references as well as skill and talent.

Thank you in advance!
