Hey, to echo what QCS has already said, we've had quite a few people such as yourself recently get into various levels of graphic design with the help of the community and it has been super positive for everyone. It's much easier to assist a new designer if they're putting in some work, however rough at first, and help them hone their skills with live feedback and tips. You could also join our community Discord where it's easier to share and diagnose designs in real time with the community.
You honestly don't need to become a professional designer, just enough ability to be able to create custom logos and accessory graphics are super helpful when presenting a fictional series. We welcome all skill levels here. And plus, if you've got a vision and a rough design, sometimes it's a good opportunity for others to help you out, whereas asking someone to design a whole series for you can be challenging and laborious.
As always, don't hesitate to ask any and all questions. That's why we're here!
