I don't have any ideas for you locally, but there's a website called Agent Query (agentquery.com). You can research agents there, and I'm almost positive I remember seeing a place on the site to post your sample query to get feedback and help with it.
Three! Wow...that just blows me away! I'm only on chapter 7 of my first one, and I started seriously working on it at the beginning of the year. Queries really do look like an unbelievably hard thing to write. Fortunately, there is a ton of advice out there, and though some of it is conflicting, at least there are places where you can post your query to get direct feedback so that it'll be in perfect shape when it''s sent out.
I love to write and the ideas have just been popping so fast I have even more on legal pads waiting to escape starts. I had so much going on in my head I finally said no more to my day job for lack of focus. I love the feeling of freeing it all on my computer screen. Good luck on your writing! I am hoping for some good input from AQ.
That's wonderful! I'm hoping to someday be in position to do this full time, but I'll have to hopefully have success with it first.. Best of luck to you on your writing, and I'll be thinking good thoughts for some good feedback from AQ on your query
