Hi there,
That's a fantastic clip - this would be a very interesting project to work on!
I'm a professional sheet music transcriber/arranger/editor/engraver, working mostly with mainstream publishers along with private clients. I'm also a music performer, educator and educational author.
This work is something I'd complete using Sibelius Ultimate, back saving into a file for any other version of Sibelius you want. I can also produce PDF, graphics, MIDI and Music XML files if required.
The fee I've quoted is for a leadsheet (full vocal line with chords above) - I could also do a standard PVG arrangement for €130, or a complete band score (vocal, guitar, keys, bass & drums) for €250.
If any of this sounds any good then I look forward to hearing from you soon.
Kind regards,
Alex
