In the meantime you could try this program  largeprintmusic.com 

I came across it when I did a google search for big print sheet music for a friend. I think I typed large sheet music in the search.  I looked at the program and thought it was sort of neat for the visually impaired.  I'm also legally blind in one eye so I bookmarked the page in case I need it in the future.

I don't have any detailed experience with the program.   If that was wrong of me to post this Mike you can delete it.
