I have been involved in several multimillion B2B businesses that relied on leads to make sales. The solution is simple, but hard at the same time: you should do this inhouse. Nobody knows your business better than you do. You understand your USPs and the added value that your services can bring to your customers. You basically need to cold-call potential customers but rather than selling your services, ask them what challenges they face in regards to the services you offer. That way, you don't get a "sales call", but have a conversation that the potential customer actually finds interesting. During the conversation you might mention that you can help them address several of the issues they are facing, and can convince them of the added value that you have for them. Selling is easy if you understand that you have to offer a solution to your customers problems rather than just trying to push your product. In order to find contacts you can use the company's website, LinkedIn or Google to find the names of the persons that you could contact. Cold-calling is still the most effective method in getting sales, especially since you only need a couple of new sales a month, so you should really focus on that! If you want to talk in more detail about how to best approach your prospects, conversation tactics etc., don't hesitate to give me a call.
