If it's such a million dollar idea, then finding an investor to cover the startup costs won't be an issue. Anyone can make a 125 page magazine, the issue lies with making one each month and keeping the ideas new and non-repetitive, in short, the long term business plan. I think that most anyone would find it near impossible to do that as an individual without a good team of writers. The team of writers is also essential unless you happen to be of such a talent that you can vary your writing style and opinions and such from article to article. People like variety in the articles they read not just in the content but the syntax, style, attitude of the writers.
