Accurate Business List using SIC Codes

I'm gearing up for a new outbound campaign and need a clean, well-structured list of businesses matching the SIC codes I'll provide. Whether the code points to a retail store, a restaurant, or any other service provider, accuracy is essential.

Here's what I'm looking for in the spreadsheet:

Business Name
Street Address
City
State
ZIP Code
Phone Number

Please ensure all information is verifiable and up to date, and remove any obvious duplicates. I'm happy to receive the file in Excel or Google Sheets — whichever you prefer — as long as the columns are clearly labeled and ready for filtering.

Before you begin, I'll share the exact SIC codes along with any regional preferences. Once you provide a small sample, I'll review it for accuracy, and upon approval, you can proceed with the full list.

If you're able to work with public databases, online directories, or your own proprietary tools to source this data, I'd love to hear more about your approach — and roughly how many records you could deliver within the first week.
