Mixed Data Entry to Database -- 2

I have a collection of records that include both numbers and text. Some of the material lives in scanned paper documents, while the rest sits in digital files such as PDFs and old Excel sheets. I need every piece of that mixed data keyed, validated, and migrated into a single, well-structured database so I can run queries and reports without worrying about missing or inconsistent fields.

You will receive:
• PDF and Excel downloads
• High-resolution scans of the paper pages

Your task is to transcribe every value, tag it to the correct field, double-check for typos, and hand back a ready-to-use database file (MySQL, Access, or SQLite—whichever you prefer, as long as it runs cross-platform).

Acceptance criteria
• 100 % of source records captured
• Text and numeric fields separated correctly
• No duplicate or orphan rows
• Final dump opens error-free and passes a spot check of random samples against the originals

Please let me know which database engine you plan to use and an estimated turnaround time once you see a sample of the documents.
