Don't reinvent the wheel and try to generate another list. Someone's already got the list, and is already selling devices to the appropriate individuals.
Use existing sales channels. Find channel partners who are already selling to the customers you've targeted, devise a partner agreement, and you will instantly have access to their existing sales channel.
Think of the sales channel like a roadway, the more individuals trying to make their way in independently, the more congested it becomes, and ultimately, the more difficult it becomes to actually reach the decision maker. Find a channel partner and "Car-Pool". Save yourself a great deal of time and effort - easily worth the cost of an agreement.
