There's always opportunity and hope Lawrence. As they say, there's 'riches in the niches'.
All you need is 100k people worldwide as a market and they can be the most loyal people who love what you do and buy a ton of stuff. Just create a place where they want to hang out and give them something of value.
A quick strategy might be:
1. Build a site (Wordpress is quick, cheap and easy)
2. Create a free shortened version of your ebook (or something similar to give away) - Called a Lead Magnet
3. Advertise it on Facebook to drive people to your site
4. Capture their email address before they download
5. Set up 3-4 welcome email with content so they buy into your expertise (You can do this in Mailchimp. The automation feature is now FREE)
6. Sell you full price ebook to them on the 5th email.
7. Keep them as advocates and sell them more stuff.
