SOLUTION
I separated the copy into sections that could be paired up with the images the client provided, and created icons that match the subject of each section. I kept all of the complex illustrations at the top of the document to highlight the process and timeline. This is because we needed a visual representation of the main stages and the client did not have photographs to show this. The icon background was also created to tie in the illustrations and icons together and make the piece more cohesive overall.
