a real developer, take a commission to polish the game to completion
What do you think is the hour rate of a real developer? And how long do you think it would take to "polish" the game? Or rebuilt your prototype, for that matter.
You might find an amateur hobby dev that is willing to take on this task, but you will not find a real developer that works for pocket money.
You use ai. Ask an ai. They are good for this type of information gathering and for getting estimates. You should still doublecheck any crucial information, because ai can hallucinate and just make stuff up, but reading information random strangers claim on the internet is not exactly reliable either.
This was the answer I got:
cost estimate on building a small computer game, if you hire a developer for the task.
A small computer game typically costs $10,000–$100,000+ to build with a hired developer, depending mainly on scope, art quality, and whether you hire a freelancer or a studio.

Using AI to replace employees, including developers, is looking more and more like a scam by ai companies. They try to sell their services and that service is costly and can not deliver, only imitate. If imitate is all you need, you might be fine. Or if there are no great risks. A hobby developer creating a game does not have to deal with customers running away, because of all the bugs. Some will not visit because of the ai, but it's a hobby, who cares about success, as long as you have fun making the game you could not have made without ai. I see this similar to all the sophisticated game engines. Boiled down, many a game is just an elaborate level for rpg maker or another engine.
