Where can I order a game engine? and what is cheaper? plugin or engine?

Question

Android

I came to the conclusion that the best solution would be to order your own game engine. The matter is that even on a python game development will be too long. I generally keep quiet about other languages ​​...
There is already a tested language that suits me. These programs like scratch , tynker and mblock all use a great visual programming language and it suits me the best . I am satisfied with the same option as Kodu Game Lab. It completely solves my problems. I found out about the prices, it's even cheaper than I planned, only 100,000 dollars for the engine, the development time is half a year. But I can't find anyone who makes these engines? I just don't know the correct name for the procession to find developers....
It's easier for me to make a corporate product once and forget the programming problem forever.
So tell
me 1. What is the correct name of a person who develops game engines? speciality? otherwise I have a problem with the search.
2 What will be cheaper? the game engine itself? or a plugin for example under unity? is there anyone who made plugins? how much is it? how fast can they do it?
3 Perhaps someone knows where these people are named what they do to order game engines?
Thanks in advance....
It's just that even if we compare the waiting time for the development of the engine and then the speed of development, it will be much cheaper and faster....

Answer 1

I would advise you to start by looking for a technical specialist who would help formalize that mess in the question and in the problem statement.
For example, it is impossible to answer the question "what is cheaper - an engine or a plugin"; the required functionality of both the first and the second is unknown.
Then, you have a clear misunderstanding of the term "engine".
In general, game engines are made by programmers.
