Compile Each of 5 Assets from Unity Asset Store into a Shooting Game

I have Another 5 Complete Assets from Unity Asset Store. I just need a Developer to turn each one into a complete shooting game when you press the 'play button' inside Unity , and also to write 5-sentences comments for each function used, to explain what the function is trying to perform (so we can see why we cannot do without that function for the game to properly execute). Milestone in 5 phases. Separate top-up and release as each project is completed and explained. So total fee /5 is each milestone payment. Also, please take note: Each Asset sent to the developer's side shall be compiled into a completed "Shooting Game" first, before the second asset will be sent over to the developer as well for the same treatment. This standard/ treatment is applicable to all the 5 Assets in this project.
