I'm a big believer in supporting and helping other authors. While some people see publishing & promoting as a competition, there are lots of other writers out there that like to help and teach their fellow authors the DOs & DON'Ts of the biz.
One good site to check out is: www.sfwa.org/other-resources/for-authors/writer-beware/
It warns of & lists reported scam publishers, agents, promoters, and such.
NOTE that any "Publisher" that asks for a large start up cost is more than likely scamming you as there are free publishing sites that will do the majority of the same work these "publishers" claim they will do.
CreateSpace is one such free publishing site: www.createspace.com/
