JamesCarr I'd echo what Mark has suggested as a starting point. Sharon is great here. The other idea I had was perhaps to work with your account team, share with them that you are looking for more training in this area, and see what options might be available outside our listed options. Perhaps there's a discussion on what's included in your existing offering from Quickbase and what would be a better fit for you from a customer experience perspective. It sounds like you are interested in expanding how you use Quickbase but could use expertise alongside you as you learn.
I'd imagine we have a few solopreneurs in our community who you might be able to work with in the event Sharon's content isn't what you are looking for.
