If you aren't able to find a place where you can take a picture with a geisha then you might perhaps be able to find someone with geisha clothing; Like perhaps an Asian friend who is intrigued by geishas might have an article of clothing. Or if you have an Asian friend they could dress up as a Geisha and that way you can have your picture :)
I'm pretty sure you could buy a japanese kimono online.
