If you want my two cents, I really disagree with having an outright goal of making money. I don't want to be harsh, but chances are you aren't going to net a profit, or even come close to breaking even. So starting out thinking that you're going to do that is only going to lead to frustration and wasted effort on your part.
Instead, focus on doing something you love- if you enjoy web development, do that. But planning on making a profit by entering a saturated market is only going to divert time and effort that would be better spent learning and getting better at what you love.
As you do learn and get better, eventually you might stumble across something that makes you money. But don't worry about it until then.
Think about it this way: which person is going to be more successful? The person who says "well, I'd like to own my own business, so I guess I'll sell XYZ", or the person who says "I really have a passion for XYZ, and other people seem to be interested in what I'm doing, so maybe I could try to monetize this somehow"?
Like I said though, just my two cents.
