need some help.

Hey guys,

As some people know on here I'm going to school for Audio Production and well I am now entering my last month of schooling. This last month is going to be working on my portfolio that is worth 40& of my final mark. Now what I'm asking for help on is I need 3 videos with no Dialogue about 30-50 seconds long that i replace the sound to. I cant use music or the main idea is to not use music its to design sounds.

So for example so far I found a trailer (below) that has no sounds just music. in this trailer I'm going to take the fighting portion and put noises over the video of the fight.

if you guys can help me find videos to replace the sound of I'd appreciate it very much.
