If you have a first chapter, send it with a short covering letter to a literary agent. In the UK we have several Writer's Yearbooks. However, check and double check for spelling, typo's and punctuation... and do not rely on 'spellchecker...'
What's the book about? I might be interested in helping you
I suggest you do a book entirely original, not ba<x>sed on the idea of OLLA or something like that. Be original.
Then it won't be your book.
