In my way for finding a business's idea, I noticed that these idea might required a certain amount of money that I don't have, I'd like to ask you what kind of business would you do to make money for your main project ? I've heard many people talks about web design or digital agency, even thought I know a bit about I don't want to be a webdesigner should I create a team ? and then make'em work for me, or do you have some business that does not require any high capital ?
You might want to search around in the forum. There's dozens of threads talking about ways of making money.
