I've been doing this a long time...over 10 years. My ebook targets a niche area for selling domain names and that's local to your area. One of the tools I give you is a list of 166 common keywords that will help you find available domain names to register. This list will help you find local domain names like newyorksushi.com or miamicondos.com that you can then sell to local businesses. I've done this many times and it really works! Last month I sold 2 domain names for $200 and $300 and this year, I've made over $8,000 just in domain names sales. I find it's much easier to sell a domain name locally than internationally. What inspired writing the ebook was a discussion over at DP forums. You can see the discussion here.
