they're a little tricky since some can be filled with words and others not... i did some looking around at others' suggestions and i think starting price of $0.50 per page (depending on how heavy it is 文字 wise) would be my preferred stance!!! i'd just have to look through the material and then give an estimate from there, adding in any extra fees like for NSFW content -- but i'll be totally transparent every step of the way

thank you for asking!!!
