After Effects Template Edited for Technology Awards Intro Video

Hi, I have a client who wants a technology awards opener/into video produced. With his logos, colours and text added. He has chosen the template he wants and I have purchased the license for it and downloaded the AE template file. The template now just needs editing to include the content he requires, which is his logo, some text, and colours as well as a short sentence voice over to be added at the end, which I am having done in-house. Obviously because this is for a client of mine, I cannot guarantee how many revisions/ammedments will be required, so unlimited amendments is a must. Video must be completed by September 3rd. Below is the link to the video file he wants editing.
