That's pretty open ended. Normally, I just charge a flat rate for my camera, lights, and accessories, unless it's a network news shoot, and then there are all sorts of add-ons possible.
I use my base rate and camera level as a benchmark. If the client wants to shoot on a specific platform that is significantly more expensive than my default camera, then I rent it and pass the rental cost along on the invoice, all lumped together as one day rate. However; if they want to use a similarly priced, but have-to-go-rent-it camera, then you can get pinched a bit.
You mentioned one man band, but they've already hired audio, so it's not really a OMB situation. But generally, I charge the same day rate for OMB, even if I have to string a mike. But I always try to steer them into hiring audio, unless it really is as simple as a single person interview.
