Hiring Someone To Write and Selling The Article

I have been thinking about this thing for some time now. I will hire someone to write an article about some topics then I would sell those articles with twice the price I paid the writer. Is this a good business idea or not?

If thats the extent of your plan, no. Who will you get to write? Who will buy them? Where will you sell them? What will they be about? And most importantly, how do you expect to get an article thats worth twice what you are paying for it? Any skilled writer knows what his work can go for. Answer those and you may have a good thing going.

you need to add some value before it becomes worth twice. either via editing or maybe bulk?

Even if you do everything right, I doubt if you may earn much with it, no one wants do work for little pay
