I have a story shop open but I have no idea how much writing is worth. I can write anywhere from 5pages to 40+ lol and was thinking of charging by page (~300 words = 1 page)

Here are some examples (sorry that you have to download them) This is actually ~40 pages Let me know if you want more of this for pricing purposes.

Just the prologue Also has more pages if you'd need those.

The only other pricing I could find was 2-3milsP/3 pages but that seems a bit high?
