At the other end of the spectrum is buying leads. This is also not the best option since it can be very expensive and may result in leads that may not actually be interested in your products or business. These are not great leads, either. The best leads will always be the ones you generate yourself—people who have shown some sort of interest in what you have to offer.
Just because you paid for the lead, it doesn’t mean that you should get emotionally attached to each one. Buying leads is, and always will be, a sorting process to find your next business partners. If you are terrible at the phone, either, buy MLM leads or get a job at a telemarketing company. Gaining experience on the phone is worth its weight in gold. Every big recruiter or enroller is good on the phone. Most of them used to be terrible but experience made them better.
Use a tool. You should not be explaining everything about your opportunity or whatever it is you have to sell over the phone, point them to a video, sizzle call, event in their area, anything but you try to explain it all over the phone. You can say “The first step to see if this is even a fit for you is to watch our short overview video at ________________”
Facebook used to be an easy source to tap into, but since they have formed a public company with shareholders who need to be kept happy, Facebook have changed their Terms of Service several times recently and have clamped down on a number of things that used to make lead generation relatively easy. They have discouraged siphoning off clients to external web sites and CPA offers, and have raised the cost of advertisements that do this. It remains a viable lead source however.
