At-risk PK Classroom Beginning of the Year Set-up

How would you like to make the first day of school for 400 3-5 year-old students a success?  We will need a great deal of help the week of July 9-13 to set up these classrooms. There will be minimal lifting required. The main task is to mount room signage and educational displays. This has to be done that week because 400 excited children will be filling these rooms the next week.  All materials and guidance will be provided.
