You can play with the numbers and goals all you want, but until you actually start something and generate revenue, it will all be meaningless. If your project goes like many of the others here, it will generate close to nothing for a while, and then slowly rise (or shoot up if you're lucky). Moreover, if you want to be successful you'll need to pick something you're knowledgeable about and have the skillset to create. Everybody here can pitch ideas, but do you really think we'd be better at coming up with an idea for a project than you would, especially given this limited amount of information?

There was an article recently that talked about the problem of people asking what programming projects they should work on, and how that was really the wrong question to ask in the first place. I wish I could find it again, as there are some parallels to these kids of questions.
