I charge $125 for a straight-forward studio headshot, something like this. (This gets you a handful of fairly similar images to choose from.)
Location portraiture is $275, things like this and this. (This gets you a larger set of images, different settings, poses, outfits…)
$475 for brand portraiture, where I work to come up with something really unique, like this. (Also a large set of images, with a set of the brand images along with a set of more standard headshots.)

Send me an email if you’re interested!
