Mobile Apps

Recently I have decided to help my father business digitally. First, I want to spread services locally and if we will get success digitally. Then I will expand my business national level.

I am trying to figure out how much my app and website cost. As none of the single sources provide me good much depth pieces of information.

I am confusing about getting costs from many development companies. As I got much range.

I need suggestions on how much should I pay for my passenger transportation business app.
