How long will you wait for the main plot to get rolling?
My current story gets going about three chapters in. Basically, the first chapter is where my main character meets up with the creepy lady who'll be employing him. I start half-way through some action, where he's in a graveyard running from a living stone angel with a sword. After he beats it (it was a test), the lady takes him to her shop/house. He meets the people who work for her and gets shown around. It's interesting by itself because the employees are weird and the shop-house is a bit like JK Rowling's Hogwarts or Dianna Wynne Jones' House of Many Ways (bigger on the inside than the outside), except that it likes to eat people who get lost. After this chapter, a customer arrives and he gets told to help her with her request, which is where the villains show up and the quest begins.
Chapter one and two should be about four thousand words each (about 30 book pages, together). Do you mind, or do you not care as long as the story is interesting?
