Well, my question was more about fiscal and legal status and company registration.
Since I live in the US now, I'm thinking of creating a sole proprietorship, that will allow me to declare my games incomes over my regular personal incomes... I got a nice book about how to create a company in the US, and I'm just waiting for my final visa papers to register mine.
I see a lot of people talking about making "money" with their games, but none talks about creating a start-up studio, and trademarking a logo/name/website. I think that since Construct2 is a all game making tool, it should be mentioned that at one point, if you want to make money, you have to declare it according to your local taxes and laws. It's not that it's what I think people should do, it's just that it's the legal way to make money and business.
I think the best way at first to monetize your game is to go on a platform like Desura, Kongregate, itch.IO ect ect... Share the revenues on the add royalties, while doing your best for promoting the platform and your game via free (or not) social network publicity.
I won't make you a billionaire but it will helps you find bugs or gameplay mistakes, get reviews, get the buzz starting... And then eventually contact bundles gaming sellers, or try on mainstream platform like Google play and Appstore.
I'm actually thinking of making a tutorial about the whole process, so everyone can have a good idea if they want to start their own micro studio or not.
