searching for font/brush/stamps

I am doing a site for a travel company and a lot of their print work includes passport stamps on scenic pictures. They want to mimic that look for their website. However, to make my job easier and to make more accurate stamps, is there any fonts, brush, or stamp sets that have some passport stamps?

This is a good place to search. There is a lot there, so might take some time. You can also make brushes quite easily. Just find or scan the images, If you need to you might have to select the area you need and create an image from that, then Edit --> Define Brush....
