I work in downtown Houston. Most of my cosplay shots have been 'hallway shots' at conventions, but I am interested in doing more sets—both at conventions and by appointment.
I will work with you for free if you're easy to work with—my schedule is usually packed, so having a plan & being on time is important.
I am skilled with Photoshop, but if you want anything more than basic shots, I would have to charge for my time.
I have uploaded a few shots here, and you can see lots of my photography on my Flickr page.
