Sorry to say, but it's virtually impossible to make money with poems on HubPages. Certainly not enough to support someone. It's because earning on HubPages is tied to the advertisements and in order to get people to click on your ads, you need them to find your articles in search engines. Original poems aren't likely to be found in a search because people don't know they exist. If you're serious about publishing your original poems, I would recommend compiling them into one volume and shopping it around to literary agents.
