I don't know if any of mine would be good enough for you but feel free to browse through the pics in the links in my signature and use any you like. All I ask is that you let me know which ones you have used.
Why don't you go through the photography forum on this site and p.m. some of the member who have posted here to see if they would give you permission to use their photos with proper credit given. I hesitate to even try to name names of people who have posted some awesome modeling pics to this site because I'll surely forget someone that shouldn't be forgotton. It may be that the most prolific of our gauge photogs haven't seen this thread.
