Create Audio track: Backing track for Meiko song

I am a musician and need backing tracks for performances. I currently create my own in Logic Pro X, but I'm not super proficient with it yet. I'd love help creating dozens of tracks eventually, but will start with one very simple track as a test project to find a potential partner to work with on several more. The first track I need is a backing track for the song "Reasons to Love You" by Meiko: [login to view URL] My wife and I will perform the song with acoustic guitars and vocals so we just need a track with other instruments (strings, bass, percussion). Interested parties should submit a 10 second clip of the cellos in the intro to showcase their capabilities to create high quality, realistic strings and audio. Final file delivery should be as a high quality mp3 or wav file and preferably a project file that I can import into Logic Pro X to do any necessary mixing/editing. Really hoping to find a good fit. I'd love to create lots of music together :)
