Congratulations on completing your manscript, and look forward one day to holding your book in my hands!
In addition to the excellent suggestions here, you may also want to consider a "hybrid" publisher, although it can be a competitive process to be accepted and involves a financial investment. SheWrites Press is one example.
Although do beware that not all hybrid publishers are reputable - they can be "cash cows" for the publishing houses they are attached to, and I've heard some horror stories.
Also, if you do not already, you may want to subscribe to Writers' Almanac - there are many manuscript contests out there with small presses, with the award being publication of your book.
