Models: Set a high rate. Lower it until you get enough work to fill the available time you have to model.
Photographers: Offer no pay or a low rate. Raise it until you get the model you want.
Professionals charge half day and full date rates, not hourly rates.
In a price negotiation, the one who quotes a rate first loses the advantage.
Let's do a little exercise assuming you are the photographer. You want to hire a model but you have no idea what her rate is. Your firm range is $1,000-$1,500 day rate so you quote $1,000.
Model A: Her rate is $2,000+. No deal. Even if she quoted you $2,000 first, it is still above your budget.
Model B: Her rate is $1,500. She hears your $1,000 and counters with $1,500. She gets hired for $1,500.
Model C: Her rate is $1,000. Deal. She gets hired for $1,000.
Model D: Her rate is $500. Deal. She gets hired for $1,000.
Model E: She would have done it for free. Deal. She gets hired for $1,000.
Now let's say the model quotes first.
Model A: No deal.
Model B: She gets hired for $1,500
Model C: She gets hired for $1,000
Model D: She gets hired for $500
Model E: She gets hired for nothing.
