Create a sound design for a video clip

Greetings. You need a sound design of the video (44 seconds).

The technical requirements are simple. A dynamic, moderately cartoonish style of design. The main focus is on the dynamics of the appearance and disappearance of images. The game itself is a strategy, capture of buildings and the passage of missions. I will immediately note that the sound design is not necessary in the style of the Lord of the Rings and other Middle Ages.

I'm waiting for your suggestions. Timeline's on. The cost of work is 5000 rubles.
