U.S. Marine Businesses Spreadsheet Update

Hi, I need help updating an existing spreadsheet of 7,773 U.S. marine businesses for REFEVIA Marine.

This is an existing-list verification job, not a request for a new lead list. For each business, please:

* Verify and fill missing public business phone, email, website and address where available.
* Confirm the correct business and branch.
* Flag duplicates, closed businesses and incorrect locations.
* Include source links for corrections and clearly mark information you cannot verify.
* Preserve every listing ID, URL and original value. Do not delete records or guess details.

Deliver the results in Excel, with proposed corrections in separate columns. No WordPress access is needed.

I would like to start with a paid trial of 100 records, counted toward the full 7,773. We would proceed with the remaining records after reviewing the trial.

Please provide your price for the trial and the full project, expected delivery time, and research method. Can you match and update my existing records rather than supply unrelated leads?

Thank you,
REFEVIA Team
