I do personal photoshoots at $20 an hour, but ATM I'm only doing them at night time. I may be able to work out an early morning shoot if I have time, since I'm allowed to change my hours depending.
But at any rate my booth will be placed somewhere and you can find me and my group. It's essentially first come first serve, and all the pictures are free.
This also means if you bring your group to my booth I can do their picture, but keep in mind I've limited space. The most I've ever fit is this many:

22 vocaloids lol. I also did a group of 10 Kingdom Hearts cosplayers, which was much more managable.
