MP4 Color Correction & Sound Enhancement

I need a skilled video editor to breathe new life into a batch of 35 MP4 files that range from 13 MB up to 1.2 GB. My top priority is image quality and, more specifically, correcting the existing colours so the footage looks natural, balanced, and consistent from shot to shot...
