From the first I was involved with helping Bill's clients make decisions about which agent was likely to respond to their work, and how the writer should approach that agent.
Nowadays there's a lot more hard info out there, and most of the scammers have been driven out of the agent business. But while I do a lot more with some writers in some instances, I've learned there's still a place for even a limited application of my kind of professional input. So here's how what we used to call the Customized Fingerprint has evolved.
I will read the first ten pages and the last ten pages of your ms (I won't make editorial suggestions, but I will have some idea of your voice). I'd also like to see a single paragraph synopsis of the story. Then I'll probably ask some questions. After that I will make agent suggestions with info about the agents and my thinking, and then work on the query letter with the writer. The cost for all this is a single all-in price of $469.00. You can order that service here.
