B2B lead generation research

I am looking to purchase marketing companies and am looking for someone to compile a database of 1000 marketing companies in the UK.

You will be required to create a google sheet and the information required is as follows:
Company name
Website
Revenue

The revenue should not be below £500,000 and not above £5,000,000. I am looking for someone to complete this efficiently at the appropriate price.

Future work will follow this, with more lists to be compiled in this sector.

Please provide a quote for 1000 leads.
