Swahili-English Translation Needed -- 2

I have content in Kiswahili that I need rendered accurately in English, and in some cases the flow goes the other way—English to Swahili—so I’m looking for someone who is comfortable moving in both directions. The material arrives in mixed formats: a few short documents, the text of a small web page whose focus is “Language”, and a brief audio clip.

Your task is to give me clean, idiomatic translations while preserving all nuance, tone, and any cultural references that matter. For the web page segment, please mirror basic formatting so I can drop the text straight back into the site. For the audio clip, a timestamped transcript in both languages will do.

Once finished, deliver:
• English versions of the Kiswahili text and audio
• Kiswahili versions of the small English passages I provide
• A brief glossary of any tricky terms or phrases you think I should keep an eye on in future updates

If you are a native speaker or have proven professional experience translating in both directions, I’m ready to start as soon as you are.
