All epic fantasy is secondary world fantasy. The problem is that we've abused the stuffing out of the word epic, and so some of us have started using secondary world fantasy to be clearer. A secondary world fantasy is, as hippokrene said, a story that takes place in a world that is not Earth or an alternate form of Earth.
Which cookie cutter would that be? The market depends on variety; therefore automatically assuming that publishers don't want your novel because it has X to it is not a good game to play.
It varies widely. Everybody's experience is different. To get a good estimate on self-publishing, you can go and see what Amazon, the Nook at Barnes & Noble and Smashwords have as terms for e-publication. You'll also have to decide if you want to hire a freelance editor, copy-editor, book cover designer, etc., which effects costs. If you're doing print or print on demand as well, that's a whole other kettle of fish. Some authors snag a publisher after a few months of going out with a book, and others take years. Response times are slow, but then a sale can happen fast. So we can't really answer your question because it depends on the book, luck, economic conditions at the time, etc.
Everybody moans about a lack of originality, cookie cutter molds and cliches. Meyers having sparkling vampires was completely original. And unless you're writing YA romance, Meyers book has got nothing to do with you. Even if you are writing YA romance, Meyers helps you get sales through symbiosis. If you are writing adult fantasy, Meyers isn't who you should be concentrating on. It doesn't matter if her vampires are broody emos or monstrous killers -- both are in the marketplace on a regular basis and were long before Meyers came on the scene. What you're really complaining about is that a bunch of teenage girls like the characters of Bella and Edward. They also like Justin Bieber, unicorns and five inch plastic heels, and no reason why they shouldn't. Deal with it.
And related to the thread topic, Meyers books were quite long, so again, publishers are not necessarily adverse to length and it should not be assumed that they are.
