Create a database of companies in excel

Hi, I need someone to complete some data entry work for me. Essentially the successful candidate will have to do the following; 1. Research (using the internet) businesses with 1 - 50 employees in various areas (provided upon successful application). 2. Find the contact details of the office manager/secretary/receptionist/stationery buyer for each of these companies. 3. Enter these contact details into a predetermined spreadsheet (provided upon successful application). I am looking to gather at least 100 contacts for each area (as an example, an area might be Birmingham or Hull or Manchester) Regards Mike
