Are you looking only for business opportunities or are you okay with home-based jobs as well? The difference between the two is that a job is something you do for others and get paid for it, while a business is what you do for yourself. Another difference is that you don’t pay money to get a job (at least the legitimate ones), while a business needs a set-up cost. But for most specialized work-at-home jobs, you will need some kind of vocational training to begin with. You can look at Career Step's website for vocational training courses if you are looking out for a job -

Now that you know the difference between the two, you can decide what will work better for you – a home-based business or a work-from-home job!
