Sarah - The Literary Consultancy is marvellous and I've used them since my second novel. They improve stuff 200%, I'm sure, and are well worth the money. Yes, it is expensive; yes, it's worth it. Once I've done that,
before I self-publish or send my stuff to my agent (whichever it is!), I also get my novel professionally edited, as I want to improve the quality as much as I can before it hits the publication process.
That way, whichever publishing route you choose, you increase the chances of building up a readership which knows it can rely on you to produce the goods. And good luck with whichever route you plan! So far, on my different experiences however, self-publishing wins every time!
