Accurate Mixed Data Entry Needed

I have several batches of raw material—typed documents, handwritten notes, and spreadsheets with figures—that all need to be transformed into a single, well-organized digital dataset. Most of the work will be handled in Microsoft Excel and Word, with occasional input through web-based forms.

Here is what matters to me: the data must be 100 % accurate, formatted consistently, and delivered on schedule. Speed is important, but not at the expense of precision or confidentiality.

Deliverables
• A cleaned and fully validated Excel workbook (or Google Sheet, if you prefer) containing every text and numerical field I supply
• Source documents returned in their original state, plus a brief change log outlining any ambiguities you resolved
• Final hand-off within the agreed timeframe

When you reply, focus on the depth and relevance of your experience with similar mixed-data entry projects. That context will help me choose the best fit quickly.
