How to generally estimate the cost of mobile application design, for example, 1 screen

Answer 1

You will not be able to estimate the cost of 1 screen due to 2 important conditions:
1: The screens are different. For example, there is a splash screen (Youtube app: "white background, red icon") and a map screen (GoogleMaps: "map, map controls, additional displays, server communication, etc.). It would be foolish to rate these 2 It's for you as a customer to say: "Pay me 5,000 rubles in 10 ruble bills. What's the difference that it's 5t.r, that it's 5t.r.?"
2: Each performer evaluates their work differently, depending on their skills. You can hire a drunk Uncle Vasya as a driver of a cargo gazelle, or you can hire a professional racer who has several golden cups. Yes, they will do the same work, but how qualitatively, on time, and in the amount of costs?
