@ behoove,
i think you have it in you to make writing a career. Perhaps you just need to go to a writing workshop to get more ideas. Write a short story, once you have the draft ready, it is as easy as sending it to publishing companies. They care more for the story and presentation and they will edit the grammar.

I have great ideas to convert to stories but i have writers block!. I just can;t seem to go beyond a page or two. But hopefully in future, i will succeed. If you wrote that in an hour, you are quite imaginative. You should have no problems writing a short story.
