Hello! I am a pro musician and I also transcribe music as a side job. I use Sibelius (a computer program) to do my work, so the charts you get will look nice and be easy to read. It is a great investment to have nice charts for your band. Rehearsals and recording sessions will go WAY faster! Besides that, you will seem more professional and it's just nice to have charts for your music. I can even make charts for a whole album if you want :)
