After realising that the copywriting field is not for me, I became interested in the lead generation service. I know that it consists of building lists of people and businesses who might be interested in a product/service from other people and businesses and then selling the list. The simplest method I know about is collecting contact details from published press releases and then listing these details in excel. But can someone, who is already doing this, suggest me how should I approach the lead generation business? Thanks!
