I need to identify ebooks IN ENGLISH for sale through affiliate 
programs (at least two-tier) that focus on tax savings for home 
based businesses in the following 20 countries:

Australia
Bahamas
Bangladesh
Barbados
Bermuda
Canada
Grand Cayman Islands
Irish Republic
Jamaica
Kenya
Liberia
New Zealand
Nigeria
Singapore
South Africa 
Tanzania
United Kingdom
United States
Zambia
Zimbabwe 

I tried some Google searches using: home based business taxes ebook + Australia.

But, could not identify anything suitable.

This isn't your answer, but there is a batch search tool that might this easier:

I put those countries into http://SearchABunch.com with universal keywords:
"book small-business tax-strategy"
