I suggest using DeepL for translation. I have checked their buisiness model and they seem to allow for 500k characters of free translation per month. All i think you need is an email address. As far as i understood it those translations can be used in commercial products.

The translation are a magnitude better than what we currently have. Example:

Current:
"Elsa" "Firefly told you have uncanny abilities."
hero "All, she said, in not true. If she says it's hot outside, I will put on mittens. "
"Elsa" "You says that for no reason at all. You can trust her, I came because of her request."
"Elsa" "I don't have much time, unfortunately. I have to go to collect dresses for a party. Let's do it fast. Probably later I will allow you to take more pleasure."

DeepL
"Elsa" "Firefly said you have exceptional abilities in certain areas."
hero "None of what she said is true. If she says it's hot outside, I'll wear mittens."
"Elsa" "You shouldn't say that about her. She can be trusted and there's no need to be modest, I came here at her request."
"Yes, she seems to keep her word, you can do business with her."
"Elsa" "I don't have much time unfortunately, I still have to go shopping for outfits for the ceremony. Let's make this quick. Maybe then I'll let you really mess around with my body."

You can immediatelly see how much better and smoother the translations are. From the punctuation, over the correct use of commas to the better vocabulary.
