Email scraping / Email Data (B2B)

Looking for somebody who has experience in scraping large volumes from UK directories. I expect individuals to recommend the most suitable directory based on experience (ideally provide a sample data set of information scraped within the last 30 days - min . 500 records to verify). Please do not ask about categories - we want all categories which make sense - so no theatres, doctors etc. just normal UK businesses which will look at their email on a daily basis.

Cost should be for an initial 50k trial (our max cost for this is £150) - we can then talk about making this ongoing.

If you already have a data list which is no older than 90 days please provide a verification sample of at least 2k to verify and cost (again for 50k to start).

Please do not reply if you have no experience in this. Replies posted via the questions section will be ignored (unless they are questions!)

To reply please start your email with "sunshine", so that I know that the full brief was read and understood.

Thanks!
