My ex business partner did the hardware design for our prototype and scored a super helpful brilliant guy out of Nigeria on Fiverr that walked him through everything he needed. So I can honestly recommend this route.
The use case we had was actually pretty similar to OP, we had some basic design in EasyEDA and were looking to bring it to the next level for proper prototyping.
The business failed for several other reasons, but lack of solid hardware design (admittedly, ours was a pretty simple design) was not one of them.
Fiverr honestly goes pretty hard if you are running lean. I saved about an order of magnitude on trademark fees by having someone on Fiverr who had done them many times before walk me through the process instead of paying a lawyer to do it. I’ve also used it in the past to get acceptable (not great, but good enough to put on contractual letterhead) logo designs for extremely reasonable pricing
