I typeset (engrave) new and old music. I also produce examples for thesis, dissertations, and journals/professional papers. I also have written a The Ticklish Guide to LilyPond, the primary environment I typeset in.
TL;DR: If you are interested in my services and flexible pricing, contact me at email@example.com.
Here are a few good examples:
Bach: BWV 598
Rachmaninoff: Op. 23, No. 10
Brahms: How Lovely Is Thy Dwelling Place
Joshua Nichols: Chorale for Solo Marimba
