No publisher or agent will accept unsolicited work from an unknown author.
You should try "querying". Instead of sending the whole thing, send a small sample attached to a resume. If they're interested, they'll ask to see the whole thing.
Ask the publishing company what they are looking for in a query letter (or go to their website if they have one). Do what they ask and then cross your fingers and hope for the best. That's your best bet if you don't know anyone in the business.
