National Online Guidebook for Business
Each participating country has its own guidebook on starting and running business there, with a unifying website.
It would be like a travelguide collection for businesses and entrepreneurs. - Think Lonely Planet for business.
Open source, peer-built, checked by legal experts.
Each book or 'country section' on the website would have sections on Banking, Tax, HR (wage guides, employment laws and so on), Demographic data, specialties of the nation (e.g. a country that specialises in ecological conservation and solar power / dairy farming / chocolate / genetic research / forestry / medical technology / pharmaceuticals / systems engineering / etc. / whatever), geography, currencies, education, tips, advice from established local businesses etc. The book would be reviewed and updated annually or whenever there's a big change in relevant policy etc. The book would be available as an e-book and possibly also in print (or maybe on an 'order to print' basis).
The website would be a unifying platform where countries can interact and be compared to help choose business locations. It would also include facts and figures, as well as 'how to' guides (e.g. 'how to apply for income tax in this country' / 'what you need to incorporate here' / 'how to get seed funding in this country'). There could also be an 'ask to answer' function allowing people to directly approach people in the know with specific questions.
A main point here is that it should all be really easy to understand / follow (like the 'For Dummies' books), easy to navigate and easy to read. There should also be an emphasis on efficiency - instead of reams of rambling information, present it all in a very to-the-point manner (except if, say, an ask-to-answer asked specifically about personal experience or a story about something). So any videos should be to-the-point and straight-forward, not elaborate and full of catchy songs and things. Think functional, pleasant, pragmatic and minimalist.
