Calling Sales Leads for Feedback

Hi Kayleigh,
Would you be interested in this new job. We are looking at calling up either 100 or 200 customers who have requested a quotation. These are all leads that have not been converted to orders. The process would be very simple and would involve collecting some feedback as to why they didn't choose our company.

The call would go as follows.

"Can you help me please?"
"I am working on behalf of Portfolio Display, whom you recently requested a quotation on XXXX"
"you didn't proceed with the order, can I ask what the problem was?"

That is it. I have a spreadsheet with contact names and what they asked us to quote on. We want as much genuine feedback as possible to find out why they didn't convert. Coming from outside the company I feel we'd get a more genuine response.

If you are interested what would you charge per 100 calls?

Thanks
Rob.
