Personal Text Translation to English

I have a piece of general-interest content saved as a simple .txt file that I need rendered into clear, idiomatic English. The text is strictly for my personal use, so while accuracy matters, I’m mainly looking for a natural flow rather than formal, publication-level formatting.

You’ll receive the original plain-text file and, in return, I’d like:

• A clean English version in the same .txt format
• A short note flagging any phrases that were particularly hard to translate or that might carry cultural nuances

Because this is everyday, non-technical material, no specialist terminology is involved. A fast turnaround and total confidentiality are appreciated.
