Video and Audio Editing

We need high quality, professional editing for video footage from a 3.5 hour event. We have one main camera and secondary camera (about 45 minutes of footage), and a separate audio file that needs to be synced with the video footage and edited. We have PowerPoint slides that can be interspersed where appropriate. We have timings for each segment of the presentation and some preliminary notes. Please see details of the videos that need to be produced and attached timing breakdowns. We expect overall video segments to be edited to match the flow of the presentation, pauses between presentations or minor audio blemishes (coughs) to be removed. We want questions and answers to the questions to be made into separate files.
