Hello! I'm a U.S.-based PHP/Wordpress Theme/Plugin developer, who specializes in Twilio integrations. I've build a number of very advanced systems for SMS and call functions on the Twilio platform, including advanced IVR, call routing, scheduled reminder sending, and much more. Some applications are native PHP, and some are integrated tightly with Wordpress (highly recommended). I have a number of solutions to your problem ready to go, and can get you up and running in just a few hours.
