Quote - Still looking for specific dollar amount suggestions per frame and per character creation/concept... :) Alicia

Call up graphic companies and pretend you are in need of their services. Present them basically with the concept that this guy presented to you, and ask them how much they would charge you per panel,  frame and per character creation/concept etc.  Ask like it's you in need of their services, not like you are there to get prices in order to compete with their services. 

Then undercut the price by 10% and present that price to the guy who has asked you to do the work.

"It is good to see ourselves as others see us. Try as we may, we are never
able to know ourselves fully as we are, especially the evil side of us.
This we can do only if we are not angry with our critics but will take in good
heart whatever they might have to say." - Ghandi
