Franz Schubert Octet D.803 — Transcribe Clarinet Part to Flute

I’m looking for a musician/engraver with strong classical music notation experience to transcribe the B♭ clarinet part from Schubert’s Octet in F major, D. 803 into a clean flute (C instrument) part.

This is a careful transcription/transposition, not a creative arrangement: the B♭ clarinet part should be transposed down a major second while preserving the original rhythms, pitches, articulations, dynamics, slurs, ornaments, etc.

Urgent: First movement

I need the first movement completed within 2 days, as rehearsals begin then. The remaining five movements can follow afterward.

I have provided:

The original Bärenreiter Urtext PDF (authoritative source)
A MuseScore file and MusicXML/MXL file of the first movement created by a friend, already transposed
The existing files contain quite a few mistakes. They are provided for reference, but the original PDF should be treated as the authoritative source and the transcription should be carefully checked against it.

Deliverables

For each movement:

Clean, professional engraved PDF flute part
MuseScore (.mscz) file
MusicXML (.mxl/.musicxml) file

Classical music engraving experience is essential, including accurate handling of articulations, slurs, dynamics, ornaments, tuplets, repeats, and navigation markings.

Please let me know your experience with classical transcription/engraving, notation software, price for the first movement, and price for all six movements.
