Google it. That is the quick solution to leads. You will get thousands of possibilities. How do you know which are legitimate and qualified?
You can have a look on sites that specialize in listing providers and rating them as to legitimacy.
Preditors and Editors: http://pred-ed.com
Although this site has become the most referred when someone asks about a business being legitimate, it is not one that can be without possible faults.
I am not that impressed with their definitions, personally. I have touched on those industry definitions in a previous post. there is a difference between a company offering author services, a small publisher and the antiquated term of vanity publisher. When the only options were to get a publisher or publish yourself, the term vanity publishing was coined. It designated someone that thought their work was worth publishing and could not or did not chose to secure a publishing contract so they prepared their book and sought out a printer who they then paid to print off their own copies. Now there are companies that call themselves publishers, self publishing companies and the like that offer author services bundled into packages. Some host your book for sale on their site, post the book for sale on other sites and also claim a percentage of the royalties. Some provide the files you need so you can self publish. Some claim to promote your book using social media and other means. Small publishers will function much like the big publishers, but with smaller staff numbers. Sometimes the author can maintain some creative control providing input and the publisher will retain a portion of your royalties. Some may pay advances, depending on their size. Many do not. However, you will not pay for the services needed to prepare your book for publishing or to publish it. If there is a restriction to this policy it should be clearly stated.
So, a resource, but do your own due diligence as well. I’m not sure how current things are, but the last book promoted at the bottom of one of the pages was published in September 2016, so at least that part is current.
Various blogs: I came across this one that also has a Facebook page that seems useful. I did not check their resources, however, so again, due diligence on your part.
If you want a professional editor, there are editor associations you can find by doing an online search. Here you can also find prevailing rates for services. Joining LinkedIn can also expose you to a number of groups that can give you everything from self publishing tips and information, connections to editors (vet them, please) and other various service providers. Please, don’t just join up and start shooting off questions. Read back discussions first. Most of your questions have already been answered numerous times. If you don’t want to put in the time to learn or you are someone that approaches life wearing rose-colored glasses, that should tell you that hiring someone to handle it for you is the way to go. In that case look for a small publisher that offers services or a book doctor and seek advice.
Facebook: Although there are numerous writer groups on Facebook, most have turned into promotional avenues. And as most will tell you, your market (unless you have written a book for authors) is not other authors. You may be able to find a review or beta reader group if you have time to search.
This is undoubtedly the most daunting period in the life of your baby, your book. As I have said before, except for at least one good editing by another person, most of the tasks to publishing can be learned. It all really depends on where you set your priorities.
This may not be the post you were expecting with lists and lists of possible service providers. I’m not one for reinventing the wheel. There are ebooks and groups and websites and blog dedicated to promoting or dissuading use of service providers. I am more interested in you not experiencing the disappointment of someone reaching deep into your ego pocket and robbing you of your book publishing budget, without providing quality service.
Protecting yourself means putting in effort to prevent being taken advantage of. It means looking at getting your book published realistically. It means understanding the difficulty of getting your book seen among the millions available and thousands of new books arriving daily. It means realistic expectations of return on your investment.
Anyone with quality work can get published. Whether that means for you that you will make an investment in time and money, pitching and submitting, or seeking the less expensive or no expense way, depends solely on you.
Now an advertisement: WoolysWagon ePublishing offers author services and no fee publishing contracts. All services are independently quoted based on the package of services you need to self publish. They will always come in under the majority of professional pricing. They will never beat fiverr. 😉 Quality service at non ego prices.
