I'm curious to know more about this project - are you looking for arrangement, transcription, engraving or something else?
I'm an experienced producer of sheet musician all formats, using Sibelius Ultimate to produce publisher-standard work in any format you need. Costs will naturally vary depending on how big this project is, but I guarantee VERY fast and accurate work.
This is my first project bid via this website, but I assure you I won't disappoint.
