Gather email addresses of UK companies

I have a list of 158 UK businesses for which I’d like to acquire person specific email addresses. I am looking for the email address of a decision maker, e.g Director/marketing manager/sales manager. I do NOT want generic email addresses, e.g info@xxxxxxx.com

I’m looking for someone who has the ability to phone up these UK companies and use techniques/methods/your unique skill to acquire the aforementioned email address. (Yes, you will need to phone these companies as I’ve already done internet research and can’t find the requisite email addresses)

I appreciate you won't get all 158 person specific email addresses, but equally I wouldn’t expect a 0% success rate either.

You just need to note down the email addresses and forward them to me.

Due to the nature of the job role only people who can phone up UK businesses during normal UK business hours should send a proposal.

I have lots of other data that needs completing and cleansing so I would like to find someone I could work with long term.

► Please start your proposal with “phone UK companies” so I know you read the job advert properly
► Confirm that you understand this job involves ACTUALLY PHONING uk companies and speaking to them, NOT data scraping.
► Your proposal should be an hourly rate.
► Please state whether you can start immediately

Thanks
