I have a portable white backdrop setup and can shoot almost anywhere.
I have two 600 watt battery powered flashes with several lighting modifiers, two smaller battery powered 200 watt flashes and two large studio 2000 watt packs. I currently shoot on a sony system.
Rates vary based on production needs. Email me for more info.
For Headshots I charge $200 for 3 looks and 3 edited photos.
