Best path to small pdfs for Web/print from scanned music manuscript

I am an old-school classical composer and have a trove of my old music manuscripts that I want to get scanned and offer on the Web, until such time as I can afford to have them professionally engraved in electronic file form (in Sibelius e.g., which will cost me thousands of dollars to have done). Hand-engraved music looks much like text plus a little line art (with the staff lines as the only purely straight horizontal parallel lines), and I gather from my researchy so far on this and other forums that the best approach is to have them
 
- scanned to TIF
- Probably either B/W or grayscale,
- 200 or 300 dpi
and then
- converted to PDF,
- possibly Optimized in Acrobat in various ways (especially background suppress, since some of the old paper is yellowed, possibly jpg compression of some sort.
 
If I can have my cake and eat it too, I'd actually like to have very small files for quick clean web display that will ALSO print crisp black and white copy with nice clean curves on the ties, slurs, note flags, and round noteheads.
 
Anybody have any advice or see any red flags in the above?
