Data Research - I provide job title & criteria & you find the people / contact detail

I am seeking someone to research companies in the UK, to find individuals who work there with specific job titles and then to put these in a spreadsheet with contact details (phone and email address).

The companies will be UK based, targeting those with between 100 and 500 employees.

We will supply a list of job titles, then you will carry out research to find these people, ensuring they are working for UK companies with 100-500 employees.

Looking to start ASAP. I will ask for a small sample of 20 records to check that the brief has been understood correctly before carrying on to 100 initially with scope for this to continue in batches of 100.
