Where can I place a brief for Android app development evaluation?

Question

Android

I looked at the websites of a dozen and a half studios, looked at freelance exchanges, etc.
I would like to get a preliminary estimate of the cost of developing an application for Android.
Studios are not encouraging, the average estimated price tag is from 300 thousand rubles. (less, in my opinion, is not profitable for them). On the exchanges, the price tag is of course smaller, but there are orders, and the selected freelancer will carry out the assessment.
For example, it’s not clear to me which is easier: to make an application with two types of users and a server-side API, or the same application with CRM (without a server), or even make a one-page site and wrap it in a WebView?

Answer 1

Development costs as much as the contractor told you.
you are not buying a bucket of potatoes, each performer will evaluate the cost of his work differently, while the performer will not care who is there and what he said about the cost.

Answer 2

Leaving his terms of reference on some freelance exchange, the contractor will name a range of prices, from and to. The price will not be exact, but based on it you can estimate the approximate budget.
Probably your order is not a product, and it definitely does not have a template, fixed price, so you can only find out the exact price from a specific contractor.
