I got sort of sick of having my query letter rejected by agents, since I was putting so much time into making each one painstakingly correct with their name and address. So, I made a service that e-mails out personalized query letters to about 900 agents at once.

I'm happy to improve the system if you have any feedback about it. I've decided to charge $100 for it, since it took a lot of time to put together, and it's a valuable service. (Other authors have told me that's a reasonable price, so that's where I came up with it.)
Let me know what you think.
