After thinking about thing, there are 2 things that hit me on this:
1. 700 pages....might be a bit off...try 1000+ Pages....(1000-1200 is what I am thinking)
2. Prices might be a bit much just for a role in a story.

So here are a few changes to reflect what all that thinking brought about.

Lead Character Roles - $15.00 USD
1.  The-Index-Card (Female/AURA Field Agent)
2. (Male/Investigator/Independent Reporter)

Supporting Cast Roles - $7.50
1. (AURA officer)
2. (AURA officer)
3. (AURA officer)
4. (AURA officer)
5. (Hacker)
6. (Hacker)
7.  Grargarg's Otto (Doctor)
8. (Illegal DJ)

Also note, that the story is (Horror/Mystery), the character you give me may die! But I will give away more info later on this part. All I will need from you, besides the funds, is a small Ref Sheet of the character you want to be in the comic, also you can make up entirely new characters if you want.

$0/$30.00 - Hakiri's Food Money
$0/$50.00 -  Yuuri /  Hardcandies Commission
