Here I'm going to clarify some cost questions.
For fanfiction stories, it can be anything that you may be a fan of. For example, Harry Potter, The Hunger Games, Twilight, My Little Pony. $10 will get you about 4 to 6 pages, depending on complexity. $25 will get you 8 to 10 pages, complexity withheld.
A part-by-part story has several parts, sometimes seen as original and then sequel. These are split into Part I and Part II. Depending on plot and complexity, I can give you an estimate on how much it would be overall.
A Pay per Page story is something I'm not too familiar with. A few people have requested it. You choose a set amount either within the price range or higher and give me the plot. I'll work with it as best I can and tell you how many pages I think it will be.
A short story usually ranges anywhere from 8 to 12 pages. The more complex/ confusing the plot, the higher it is. Please keep in mind that a short story requires me to fit a plot into a set number of pages, so the longer the plot, the more that has to go into said pages.
Additional Costs:
When it comes to fetish, I'm usually okay with writing it; I don't have many complaints about it. However, some fetishes are quite extreme or are something I'm not actually familiar with. Anything that makes me uncomfortable or is difficult, I will charge extra for.
Some people want excessive amounts of detail and as they say, the customer is always right! I usually try to paint the scene in plenty of detail to help picture it in the mind. However, some people want a bit more when it comes to detail. This is for them.
Smut! Smut! Smut! I don't mind writing M/M, F/F, F/M, TG, or any other pairings. However, if all you are wanting is one gigantic story of sex scenes or just sex, then this charge is for you. Sex is good, but a storyline is better ;)
