Sounds like your ready to jump in
I was pretty much in your position when I started, had read everything I could but was still a little nervous. The gentleman I purchased my nuc off said 2 things that set me at ease.
"If you can raise sheep and cattle you wont have any problems looking after bees" In his experience those that struggle starting out are usually people that have never owned and looked after anything besides a goldfish. Even if you have only had cats or dogs you will have noticed differences in their behaviour when something isn't quite right. You are used to treating for flees, worms etc either by a schedule or when symptoms present, the diseases and parasites in bees are different but the same basic principles apply.
"Bees can take care of most situations on their own" They don't need you to do everything for them just a helping hand.
My only regret jumping in like I did is I should have done it earlier, I think starting in spring would have been better than starting early summer, I missed all the early season build up and our main spring flow.
