So with this
Helm Publishing, here are the specific red flags for me:
A) Past record--I have never heard of a pay-to-play publisher turning into a royalty-paying publisher.
B) Spectacularly unprofessional website. Look at the "New Books" sidebar on the front page, for instance; the books are listed from oldest to newest, rather than newest first. Who's going to scroll down to find the newest books?
Also, it looks like an explosion in a font factory.
C) Grammar and syntax errors in the book descriptions. Do you really want to have these folks editing your work?
D) Amateurish cover design. Lots of very small presses have great-looking covers.
E) Saying "See Helm Ebooks for sale" without giving any links to same is not effective promotion of those ebooks.
F) Speaking of ineffective promotion, note that the "Events" page hasn't been updated since 2009.
I haven't read your book, Gondomir, but I don't need to in order to know that it deserves better.
