My problem.

While you can certainly and successfully create your own products and market them yourself - which is something I plan to do eventually. Like you, I wasn't as comfortable creating publishable mechanics on my own. So through my freelance connections, I'm currently publishing my Kaidan material as an imprint under Rite Publishing. If you look at the copyrights on the Kaidan material, both my name and Steve Russell are listed. I actually own the IP for the Kaidan setting. Steve Russell and Rite Publishing has a solid reputation, while I started with none.

I chose to create my materials as an imprint solely so I could get freelance assistance with the mechanics that I wasn't expert at. In the 2+ years I've been working with Rite, I've gained loads of 'training' and study of the work by Rite Publishing's creative staff.

Though I will continue to publish Kaidan material under Rite, it may not be too long before I publish something else, completely on my own, under my own publishing name, (which at this point is called Gamer Printshop Publishing - I already have an industry code of GPS thru Gamerati).

Learn basic statistics.
Learn basic writing skills.
Learn basic proof-reading.
Learn basic editing.
Learn basic type-setting.
Learn basic page-setting.

No order implied. Honestly, if you can do ok on those, you're ahead of most of the crowd.

And unless you have a lucrative day job that doesn't demand much, you don't have much of a budget to hire people to do those for you. And, you'd need to check their work anyway.
