Find me some Leads

Hello everyone. I run a sales team and we currently use google and linkedin to find our leads. This can be a very tedious process and is painfully slow. We are searching for people who: Have worked in the UK for atleast 3 years AND presently live in South Africa. Attached is a screenshot how I would search google to find me leads. There are other methods, not only using linked in, news articles perhaps saying someone is or has "moved" to South Africa etc. I will require contact details of the said person. This can be an email or the company's contact details. we have a CRM system inplace and the leads need to be "fresh", if another agent has already found someone they will already be in the CRM so I will need you to make sure that they are "new" prospects. I look forward to your reply's.
