I am looking to build out a proper MVP for a consumer product I've been working on. I have enough experience with Arduinos/microcontroller programming that I was able to build a low fidelity prototype and test successfully with several users. However, I want something more robust now to test with a larger audience, which would likely require creating a PCB.

Is it advisable to hire freelance hardware support to build this or do I need a hardware-minded cofounder? (For further context, this is not a particularly complicated device). Wanted to learn what your experiences were with hiring freelance and if you had any recommendations for platforms to use/engineers to hire.
