I also lacked the skills to design my own (working!) PCB. I started learning (MSP430 and TI RTOS) and realized that it was going to take years for me to come up to speed. However, I did learn enough to better communicate my EE design goals. Ultimately, I hired a EE off of Upwork and it was a great collaboration, and went on to design a few more simple breakout boards with them. To choose my EE, I balanced price and ability to communicate in English. The board we designed was a PyCom (ESP32) expansion board that had a handful of peripherals I needed for various side projects. Among those were a USB chip (MAX3421E), a 24-bit ADC for load cells (ADS1231), and a battery charge circuit.
