Create a Video Edit a short video and add deign elements

I need a short - 3-5 minute video edited together from 4 videos of interviews (each less than 5 minutes), some still images and logos plus need to design an introduction, ending and graphic elements (logo animation, headings etc). It will be placed on my website. I have a one page script (attached) but happy to get input on how best to structure the video. I think we will need two- three sets of edits to get to the final one. Not sure of time required so happy to receive quite once scope clear.
