Hi Rico,
I recently developed Smart Adult Gallery, a tool that can help you do this fast and cheaply. It allows easy cropping of your pictures, watermarking, and if you set your TGP templates to it you can easily have each gallery ready in less than a minute.
You can try the demo here: smartadultgallery dot com slash demo
If you need someone to do this job and don't want to use the tool, I can do it at a great price by using my tool, at around 2 cents per picture.
You can contact me at support at smartadultgallery dot com
