Call names on list supplied to identify interest

A telemarketing person to make initial contact with names I supply to identify interested parties.
1) I will be buying lists of companies operating in sectors in which we have had success.
2) I will send out emails to all on that list describing what we are selling
3) They will be sent a small batch at a time, so that the information will be fresh when they are called.
4) Data, comprising Company, Name, Email address, Telephone number to the telemarketing person.
5) They will make contact and categorise each:
A Of immediate interest
B Interested in principle, but no immediate action
C Not at all interested
