Holiday Slideshow

We need a slideshow made that has a warm feel and is like a thank you to the employees.

We have employee images (the collage image), a collection of other images, and some videos.
Please include all the images and videos you can into the slideshow.
There should be no audio from the videos. However, we would like some holiday themed, instrumental music with the video- license free music.
The video will be shown with and without music so it should look good either way it's viewed.
Please have the collage at the end or beginning- not in the middle. Have the collage show up by starting on one face and then pan out to show all the faces.
If the collage is at the end of the video- have the logo (included) fade in over the collage after it's panned out to end the video off.
The video may be shown on a loop so make sure the end and beginning can blend well together.

Something like this: https://www.youtube.com/watch?v=k3cv4JQ-IvY without the flashing lights and not quite as jumpy looking- smoother transitions would be nice. It does not need to look exactly like this but we need to have this kind of feel.
