Tangi Practical Shooters Assoc, and East Ascension Practical Shooters, both have USPSA clubs you can join. I would bet they have guys in the group that can get you there.
By all means, this^FRC Range has a drop-in USPSA practice on Tuesday evenings. I'm just getting started myself, and the best way to learn - I think - is to just sign up for a match, be safe, and show up hungry and willing to listen. It's a ridiculously welcoming community.
There are also drop-in matches at St Bernard Range on Sundays and Nick's on Sundays/Thursdays... none of those have movement involved, but it's a nice easy introduction to competition-style shooting.
Also reach out to the user @bryanbag on here, he's extremely tapped into the local matches and coordinates a lot of the USPSA stuff.
