My experience has mostly been in the realm of promotional photography for stage productions.
I'll soon add some headshot photography to my portfolio. I definitely kick butt at HEADSHOT EDITING (below)!

Pricing is currently at $100 for a one hour photo shoot, including 2 edited/polished photos.

You can have your full resolution headshot touched up for just $20.
If your photo is merely Facebook size I'll do it for $10.

Here are a few samples. Click on the image to view it full size and read a description on what's been edited underneath. These were edited for headshot purposes, meaning that they weren't supposed to be perfect. If you do want it to look as perfect as a model shot just let me know.
