I digitally restore old sheet music! No matter how battered the score has been in the past (with a few exceptions of course), all I would need would be a PDF or other image file to copy music from and some time! I could handle the rest. You can read all about what it takes on my Engraving services page.
For musical engraving, I would require a paper score all bound with no missing pages either hand-written or type-set in fairly good condition so as to ensure accurate results for the digital print out. Depending on the length of the score, budgets usually go from $60-$250 as a fixed price deal. On a per-page basis, I charge $2.50 per page on average. I prefer Paypal for payment, but if you need to send a check, send it via snail mail.
