My efforts to find a Publisher's Assistant on my own have proven futile. So, after a great deal of research, I've retained Virtual Staff Finder to do most of the hiring process. They'll screen, interview, investigate and test about a dozen candidates, then choose the best three for me to interview and choose from.
At which point, my publishing efforts will become much more effective, and I'll be able to spend a lot more of my time writing books.
My thanks to Chris Ducker of VirtualBusinessLifestyle.com for being the best online business guru in the world!
