I do things a little different than other photographers.  I charge a flat rate of $250 and that includes:
1 hour of shooting 
Unique locations- you can choose or I can find something
Clothing changes
I professionally edit the photos and typically end up with 30-50 photos.  When I say "professionally edited" I take time to make sure each image is perfect.  I also include black & white and vintage filters if requested.
I gave you all the photos on a jump drive with full print rights.  So you have tons of photos to choose from, and you can order prints yourself and save money.
This site is where most clients print from: http://processonephoto.com/round-corner-wallets.htm  and I can always help you place your order (for no charge.)
I prefer to charge based on my talent and let you save money on prints.  (Most places end up giving you 3 or 4 poses and then charge $300- $400 for prints.)
My portraits shoots are always a blast, and we'll get unique photos.
