Finding the right agent for you is a lot of work. Settle in for the long haul, it might take you a month to build a list to query and a few more to write a query.
Writer's Digest has some useful articles, but be mindful they might be out of date. Use agent names as a starting point. Look at their website. Look at their Twitter pages. See how they interact with people. Look up the Writer Beware threads here. The website QueryTracker has some information on agent response rates and turn around times, but some of it requires a subscription. Publisher's Marketplace has information (not always super up to date, but useful) on their recent sales. You can find a great editorial agent, good personality fit, loves you, loves the genre... and can't sell a book.
So yeah, settle in for the long haul. Make a Twitter acount. Follow the agents you're interested in (and do NOT unfollow after a rejection). Start building a list of 50 (or so) agents. It's gonna take some serious research we can't do for you. We're not you and didn't write your book.
