Telephone Researcher and Data Entry

We are a recruitment consultancy. I have 320 companies in a niche (Lifts & Escalators). I need to find names and email addresses of the engineering managers of these companies. All of this to be entered onto an excel spreadsheet and from telephone research calls. and then sent back to us. The project should take 3-4 days.

If this goes well and the costs are reasonable we will have a lot of similar work.
