String player/arranger needed for editing music online

I need someone who plays violin, viola, cello, or double bass and understands the fingering systems & bowing of all these instruments. The work is mainly going to be editing a simplified form of music notation for strings.
I would prefer the applicant to also have some arranging ability, familiarity with Finale music notation software, and MIDI files. The better the skills, the more work I will be able to provide.
In addition, I need some help with posting videos on YouTube, Facebook, and Twitter.
The work will likely require a couple hours per weekday.
Payment will be in Bitcoin, which can be easily transferred into your local currency.
