I'd use 23mm, I think 35+ would be too tight. You're going to want more context for the photos, and for that wider is better. The 35 will be too close and portrait like. Using what you be got, the 18-55 kit would work just fine the 16 might come in handy as well. My bet is you wouldn't use the 35f1.4 one bit.

Anyone else annoyed when family hires someone else, when they know full well that you are professional photographer?

2 will do, 3 be trouble, 4 or more forget it. You took them learn to cull them, it's not that hard. I been at it a while and I crunch through 1000 in 20 min or less.

Fine Art America has an estimated 25,000-40,000 artist, world wide there are millions of artists selling prints. It's a brave endeavor and only a few artist will be successful. Once you sell a few to friends and family it gets quiet really quick unless you know people.
