Cold calling - Data collecting

Hi First of all thanks for reading and even a bigger thank you for all those bidding on this one. Status Quo: We have a database with lead clients but miss for some their email adress and fax number The mission: Call the prospect clients and ask for their email adress, fax number Enter these data in an excel sheet or webinterface (yet to clarify). Requirements: - Native french speaker - Good communication skills Pricing: We will start with a fixed price for 1000 calls. If mission results according to our both agreed expectations then we will continue with an hourly based budget (+/-6000 calls).
