National Accounting Firms Lead List

I need a fresh, fully verified list of decision-makers at large national accounting firms that have an active interest in marketing and client-growth solutions. Your research should focus only on firms that operate across multiple states under a single brand.

Please source contacts who can realistically start or influence conversations about outside marketing support. For every contact gathered, confirm the individual’s role and the firm’s footprint so I am speaking with the right people at the right organisations.

Deliverables
• 200+ unique firms that meet the “large national” criterion
• 1–2 senior contacts per firm with name, job title, direct email, phone (if available) and LinkedIn URL
• A brief note (1–2 lines) on why the firm is likely to be seeking marketing or client-growth help (e.g., recent expansion, service launch, public statement, etc.)
• Data provided in a clean, filterable Google Sheet or Excel file

Acceptance Criteria
• All emails pass verification (zero hard bounces)
• No duplicate firms or contacts
• Each firm clearly operates nationally, not just regionally
• Spot checks show the justification notes are accurate and relevant

Let me know your method for sourcing and validating the data, estimated turnaround time, and any clarifying questions you have.
