Tele Caller

I'm looking for an experienced tele caller to verify and collect the correct contact details of the potential companies in India. I will provide the list of the companies. . We estimate that at least 100-500 calls need to be made, and the tele caller must have extensive experience in the the Steel Industry and mechanical engineering area. The surveys are intended to collect important data from the given list of companies so that we can use it to initiate the business discussions with the key business persons.. The calls should be made nationally, while adhering to relevant national laws and standards.
