There are tons of free fonts at http://www.cindysembroiderydesigns.com/alphas.html<br />This is the most inclusive site that comes to mind at the moment. I hope you find something that works for you.

None that I can think of. There are some monogram letters on this site but not free. $1.00 each or you can buy the pack. If you're just needing three letters and you like this font, wouldn't be a bad price to pay. http://www.emblibrary.com/EL/search.aspx?search=monograms
