How to get a publisher?

If this is your first novel... you have a way to go before you get published and it is unlikely you will get a huge advance. You need a literary agent who will only sign you once you've completed the novel. This literary agent will know what publishers to contact that would be most accepting of your mcript. However, I think the market is flooded with 'Da Vinci Code' style mcripts at the moment... maybe think of something new!
