In the first instance is there something you could do with your existing employer to leverage the organisation's skills/business/expertise into an online / or another area of business? This would be an idea you come up with and champion, set it up and run it.

Benefits of this is that you get to learn great skills and get good experience on someone else's time and money! If it works, great, if it doesnt, YOU havent lost anything.

I find that when starting out it is sometimes easier to begin with what you have at hand rather than come up with something new out of the blue. Other ideas will then naturally flow from this activity (thats what I find anyway!).
