Animation CutScene 30sec Unity. High quality.

Hello! I need about 20-30sec animation scene where four fighters fight each others. I have manuscript how animation should go and i have all four models. There is two human model, one troll and one minotaur. You can make animation how you want. I only need MP4 version about animation because it will come to my game trailer. Background scene will be fighting arena. (Only 4 basic walls and sand floor) if you use something else than unity game engine i can give you textures but you need to make those four wall and sand. I add image here so you see what arena looks like.
