Best of luck finding the folks you need local to Cincinatti, OH.
Have you considered opening up your requirements to include remote workers? For stuff like software engineering, you'll seriously expand your pool of great workers literally Worldwide. Demand results, and continuously shed dead weight. You'll build a great team that works because they love it, not because they just need a gig, and they live nearby in OH. If Covid showed us anything, it's that the remote worker model can definitely work, and it works well when you incorporate things like slack and google meet into standups and meetings. Plus, have all hands meetings once a quarter or so where everyone gets together and has fun and socializes and plans new bold ideas. I know it can seem scary and that you don't have control over what people are doing all day, but the results will speak for themselves. Try it! You can always go back to not doing it...
Just some ideas, because you guys are _way_ behind on getting that next release even close to going ot the door, and I am really excited to see what you come up with next.
