Music Video Editing and Post-production

I'm looking for a video editor to help me complete a music video project. I'll be supplying a Final Cut Pro project that already has some key elements in place, and I need you to add the remaining raw assets — specifically the single-camera guitar footage shot in front of a green screen, and the mixed audio (guitar track blended with a backing track) which will need to be synchronised to the performance. The video is around four minutes long and is a cover version of a popular song.
Your job is to do the heavy lifting — compositing the green screen footage using chroma key against the background video elements I'll provide, synchronising the audio precisely, and bringing the whole thing to a great result with solid colour grading throughout. The project must be worked on and returned in Final Cut Pro, with the full .fcpbundle sent back to me to finalise. Please also include a brief explanation of the key effects and settings you've used so I can make adjustments going forward. Please note that any quote should include provision for a few rounds of revisions within the agreed budget, as I may need some tweaks before the final result is signed off. Let me know if this is something you can help with and what your rate would be.
