You can start by optimizing using your keywords. After that, you may want to buy targeted traffic or a targeted email campaign.
Lead generation is not that easy but can be done. You need to first be able to narrow your niche and then use all possible marketing tools to drive traffic to a squeeze page and capture the leads... you need to capture the leads yourself. No one will give you their leads in a particular niche.
You can post in popular forums that are related to your niche and offer them a free report. Everybody likes Free. You will get many leads.
