Short Formal Letter Translation

I have a brief Spanish letter that must be rendered into polished, native-sounding English while preserving its formal tone and original intent. The text is concise—no technical jargon—yet it is important that the phrasing remains courteous and professional, as the letter will be sent to a business contact.

You will receive the original document in an editable file. I expect:

• A clean English version that mirrors the structure, salutations, and closings of the source
• Careful choice of vocabulary to maintain a formal register
• Delivery in the same file format within 24 hours of acceptance

Before starting, please let me know if you spot any ambiguities so I can clarify them.
