So, do you have any connections with publishers? Any relatives, colleagues, friends, friends-of-friends, etc.? Even if you don't know of any, are you willing to post about my search in your blog? Something along the lines of: "My friend Evan is seeking a publisher for a collection of his humorous advice-column letters about the extraordinary and supernatural, as seen at AskDrEldritch.com. He's pretty funny,* so if you, or your friends, or your friends-of-friends have contacts in a suitable publishing house, they can email him at email@example.com."
(*Feel free to elaborate effusively, if you like.)
The query letter I've drafted is here, and here as a downloadable Word doc. Any, ideas suggestions, help or contacts you can send my way are greatly appreciated! And if you're the person who makes the link between me and a publisher... let's just say I will be very grateful.
