Sweet Fashion, film is great but it is a commitment. Scanning takes time, and the sub $1k scanners are a real pain. Printing in a darkroom is faster than scanning, but I'm not sure of your comfort level with color darkroom work or if you even have access to a darkroom.
I wouldn't shoot beauty with film, unless I wanted the film look. I don't think film is clean enough for commercial beauty work. Maybe with chromes, like 100G on 4x5. Its just a matter of client expectations. I actually like beauty on film, but really only for my book. Fashion on film is great.
That being said, a used Microtek 120tf is a dedicated MF film scanner that produces good results with the glass holder. The regular holder can rarely keep the film flat. I bought one new three years ago after my Nikon 9000 was destroyed during a move. I couldn't find another one so I got the Microtek. Quality wise its close to the Nikon, its just slower and the holders are not as good. Silverfast software is pretty OK, a little buggy. OK, a lot buggy, but it gets you nice color. I use the Microtek scans for my book or when a client wants FPO images from a film shoot before they get a drum scan for press. The FPO scans I've done at 2000 dpi are good enough for publication. I've had double trucks printed from the 2000 dpi scans.
If you have a Canon or Nikon I'd shoot that until I could get a P21+ or a Leaf 54s, at least for beauty. Be advised that the H with film acts differently than the H with a back, just a little slower response.
Good luck with all this!
