Greetings,
I understand that you are looking for someone to convert your PDF score into MIDI file, am I right? You said that there is some example - but I dont see any attached files (freelancer is doing it all the time). Anyway, I know how to do it, and I can do it for you. I will place all notes into Sibelius project and export it as MIDI file. Please, check out my profile to get a better impression in my productions quality and my skills. Feel free to contact me so we can discuss about it, I have no idea how many pages you have to convert.
