Many companies (and writers) offer services to writers. Having someone edit your story is a good idea. Having an agent or company help you with setting up a strong structure might be helpful.
However, what is there to protect writers from poor service, someone setting up shop without valid prior experience? I’ve heard many, many stories of poor editors, promised services left undelivered, etc.
I don’t think writers should have to pay for interviews or reviews – yet some writers have found themselves suckered into these “services” with the promise of sales.
The writer needs to do some background research, ask for credentials and satisfied (perhaps even unsatisfied) customers to chat with before purchasing services. Don’t go by the reviews the company or person promotes on their own website, unless you can reach out to those people personally. Too bad there’s not a yelp for writer’s service.
Recently, I did my own research on a few companies. I googled the “authors” they’d used as their positive reviews. The first author/service reviewer I couldn’t find at all – not on amazon, no website. It well could be she uses a pseudonym, but why would she not use a name people could find? Another reviewer claimed to have gone from no sales to 100,000 sales in a month’s time span. When I googled this author, they had one ebook available for purchase. It did not rank very high according to the sales figures I have access too; I found the claim to be overstated. While he may have doubled or tripled his sales, I don’t see any evidence that he has become a best seller on any available websites or lists. Consider the reason authors might make these claims: to be featured on the website in order to garner more readers and sales.
Do your research, writers. If a writer or service, company, or agent won’t or can’t supply you with references or a tax id # or a business license #, what’s your evidence they can do the promised job?
