I think that you need to be assured of your photo capabilities before working with models.
I'm pretty happy with my camera and equipment control, plus I have the necessary studio lights, backdrops and reflectors all gathering dust.
This is the same as shooting weddings or any other non-repeatable event. Although you
CAN repeat a session with a model, it is (IMO) necessary that you get decent images from the start or you will lose your models.
Part of my original post I asked what is a 'look'. I think part of my issue is that I can pretty much guarantee to get at a good image of a model, but I am not sure what THEY are looking for. HOW many different looks, and what constitutes a 'look'? Is acouple of different outfits sufficients, or are we looking at significantly different poses, facial expressions, locations, backdrops, 'stories'? I don't want to underperform. (Now there's a surprise, a guy suffering from performance anxiety!).
I recommend that you have a selection of your best shots readily available, sort of a mini portfolio.

How do you contact models for shoots? I belong to a set of loosely organized photo groups which have a wonderful driving force.
This is what I need, handholding for the first session

Having a make-up-artist and a hair stylist along on the shoot is a great help to the photographer.
