I've actually started doing commissions! It's scary, I know, but that's how I roll. Here's the info:

Pencil Sketch: $5-15
Basic pencil sketch of the character, cost depending on the detail desired. This could be a simple headshot, a bust, full body, or whatever. One character. Each additional character: $3-10.

Ink: $1-10
Hand inking of the sketch, cleaning up the pencil lines and making it look overall shiny and crisp. Each additional character: $1-6

Coloring: $2-10
This falls under three categories: black/white pencil shading, colored pencil (Prismacolor), or digitally colored (Photoshop or Illustrator). Each additional character: $1-7

Background: Free-$10
Screenshot backgrounds are free, same as solid colors. The price of the background once again depends on the detail desired.

Digital Copy/scan: Free
Physical Copy: Shipping $5

Custom UI Skins: $5-15
Once again depending on complexity. This would be for mods like Btex. All I ask is that you tell me which mod you are using so I can make sure the files will work properly before I send them to you.

Here's a list of people I'm currently working on:
Darkluck [Current/Nearly Finished]
Sooper Seekrit Person
Abominus
Gnosis
