Creating a map of the areas of influence of an object in ArcMap

We need a specialist in ArcMap. It requires creating a map of the object’s areas of influence in ArcMap. I am writing a diploma and I need to create a map in ArcMap. On the map, you need to display the MSW landfill and the nearby territory, imposing a grid (cells with a capacity of 100 m or 300 m). And at the intersection of the grid, allegedly, sampling points with MAC values (maximum permissible concentration). And then it is necessary to show the zones of influence of this polygon, which are distinguished by the values of the MAC. Perhaps I can explain the problem better when I talk. And since I’ve only recently started learning about ArcMap, I’d like to know how to create this kind of map myself. So, could you, when you create a map, do a screen demonstration in Skype or zoom with explanations? It would be a kind of lesson.
