Economic Internships available in Htx?

I’m an Economics major about to start my 6th semester (junior standing).

I’ve completed coursework in micro and macro theory, econometrics, statistics, programming & databases, and corporate finance (with macroeconomics and macroeconometrics coming next semester).

I’ve noticed that many summer internships recruit very early, so I’m wondering if anyone knows of organizations that hire later in the cycle—smaller firms, research roles, or other solid but less well-known places to apply, especially in the Houston area.

Any advice from people who’ve been through this would be greatly appreciated.
