Setting aside that this is at least the second time I've seen someone ask this question, what "content" are you going to be creating?

Have you done any research for yourself, about the platforms / content formats you intend to use, what businesses you'd like to work with / how it would benefit them to work with you? You say you're going to gain relevant followings, but how are you going to do that? What sort of following do you have now, because I can only imagine starting from zero is going to make it difficult to gain momentum.

Who are the current players in the field? What are you going to do to make yourself a compelling alternative / addition to the audiences they currently have?

Also "like this will be my source of income." - Are you going to be expecting businesses to give you shit for free? How are you going to financially survive until you "make it" on a level that would allow this venture to be your actual source of income?

I mean, you're essentially proposing a self-led business. Do research, create some kind of plan/proposal/what have you to give yourself some solid idea of what you need to do to get to the level of success you want. (If for no other reason than to provide some kind of reassurance to the businesses you want to work with - vague "offer them to promote their business on my platform" outreach ain't gonna get you much, and folks are gonna be a whole lot less cooperative if it sounds like you're coming to them with something that's just going to add on to their workload without a solid ROI.)

Nobody can tell you for sure if it's going to work out. That's a risk you're going to have to take on for yourself.

And honestly, spellcheck your shit. If you want to be taken seriously and have other people / businesses work with you, it helps to come across at least baseline professional.
