and glad you found us.
Even though your scenario is a little different I think Sony now has something for everyone. Their mirrorless bodies are getting to be pretty amazing. So, what you're after is something that can handle low light and expose the shadows better. This is where Sony's processors really kick ass over just about everyone else! On top of that, the A6000 body is now a lot of bang for the buck with the recent price drops and it is only slightly larger than many point and shoots. The kit lens at 16-50mm should be all you need. With your lighting in place you only need a tripod and maybe a remote shutter release.

There are a number of Sony mirrorless options at that link. Any of them will work for any dealer. It is just a matter of whether you like to spend $600 or $3,000 for prestige purposes.
On a personal note, I can't tell you how many times I've debated with buying a Sony camera for my own photography hobby/addiction. If I weren't so heavily invested in Canon and didn't need the super fast autofocus for wildlife & sports shooting I'd have jumped on both the A6000 and A7 bodies by now. If you're a new photographer, without any glass investments, then Sony is the way to go.
