General guidelines for those who do not have college degree and are not students but they could publish an article?
Sorry to have to say it, but the first step is to assure yourself that you aren't a crank. You don't sound like someone trying to "square the circle", so the first comment was just for completeness. But if you aren't sure about the validity of your research then getting some feedback on it from a pro would be helpful. Perhaps you are close enough to some university to make contacts and talk about what value your ideas might have. 

But in the final analysis, you publish in a journal by submitting your work to the journal. If you get desk-rejected by an editor you have some information that your work isn't up to the required standard. But otherwise your work will be given to experienced reviewers for comment. 

You don't need any credential or affiliation to publish. Just quality work. 

Longer term, however, forming some circle of collaboration can help get you in the game. It can help you up your game as well. 



You don't say what you mean by "lack of support". If you edit the question to add more, I might have more to say as well.
