No list that I'm aware of but some may chime in here after a few days.
There is a place on the Lindsay site for "engraver's needed" where the general public can post a need with a brief descripton of what you want done. Those that look at that part of the site will call or email the person needing some work done.
I've answered a couple but the need is usually filled by then. Don't hurt anything to ask here or there as far as I'm concerned, you may get a bite.
