No problem, and thanks for the pm.
And besides, I think I messed up my suggestion. There is no 70-200 f/4 for Nikon, or they're not made anymore, although still available. That's a Canon lens, and it's probably too slow now that I think about it.
Nikon does make an 80-200 mm f/2.8 that's rather cheap, so it's a fantastic deal. But because of it's size, it's not what I'd call a good lens to carry around. I'd still consider the Nikon 80-200 f/28 or Sigma 50-150 mm f/2.8 (smaller size and weight), the Nikon 50 mm f/1.4, and a Sigma/Tamron/Tokina lens that's equivalent to around 18-50 mm (or something similar) f/2.8 lens. If you want to spend more money on a Nikon equivalent to these focal lengths that's also f/2.8, it's going to be very expensive.
And like I said, spend money to make money. It's an investment. If she produces poor photos, she's not going to get referred to others who are getting married, and she won't have no photos for her portfolio, which digs her into a hole. Even if she's not getting all Nikon (or Canon, Pentax, etc) lenses due to cost, she should at least try to get the Sigma, Tamron, and Tokina alternatives, which are sometimes as good, and 1/2 or 1/3rd the cost.
