I own a domain called thebusinessbible.com can anyone think of what would be a suitable business model for a residual income?
How about a small business forum with Adsense or sponsored ads on it? Your contributors would provide the content. Or, a blog with business marketing strategies? Again supported by Adsense?
I think since you named it bible why not throw up a wiki, and have users contribute to the bible. Lock the good pages splash it up with adsense and promote im sure it could work.
OR, saw this on Amazon - http://www.amazon.co.uk/Small-Busin...r_1_19?ie=UTF8&s=books&qid=1213803481&sr=8-19 How about setting up a business directory for you area? the UK?
Definitely marketable as an e-book. Hire someone to write one for you (or write it yourself), set up Clickbank, and you're off.
