you are asking about steady income. The best way (and safest) of earning steady income in the modern age is to get a job. hourly/monthly rates depends on qualification, risk, experience, responsibilities and your personal power of negotiation. Maybe some luck too.

Now if you want to take control over your money. I suggest you try to live within your incomes and watch your expenses. I will suggest you two sites. one to use and one to read.

both excellent.

Yes.  I agree with farko.  The only way one can be sure that they will have money is either by inheriting it or earning it.  If you are earning it, it can only be constant if you have a job, and keep your job.  So in essence, one must work hard doing a job in order to keep a steady income.

By having a regular job, you will always make rich your boss.

By becoming your own boss (for example, in partnership with a company which has an outstanding business model, experience and trainings) will allow you to build your wealthness. As well as to sell your own business at the right moment.

You should read the book of Paul Zane Piltzer (youngest Vice-President of City Bank, economical advisor of 2 US Presidential administrations) called "The New Millionaires".
