Oh hmm this was like 5 years ago but I remember a local post office being the closest place. I didn’t realize you needed an appt but the lady was nice she had time to see me it doesn’t take long. It was actually easier than I thought it would be once you get the picture and stuff squared away. CVS pharmacy has a background and knows the dimensions and stuff it was like $8 I think. I would suggest doing the post office route if possible.
