Hi Darren,
I'm a web-research addict and I'm considering your job post for me with the required capabilities. I use paid tools and useful search engine keywords tricks in order to extract the exact and required information.
I have a lot of experience searching personal and companies information all around the UK, US, CANADA, CHINA and many more. I have a LinkedIn Sales Nav account, can do adv. search technique and some useful tools to collect the exact email addresses.
The quality of leads:
Each lead goes through a triple layer quality check that is each lead with an email is processed through an email verification tool, then checked manually and run through our servers before deemed as verified.
Looking forward to work with you!
