It's very hard to be young and want to do things. People automatically assume that you're immature and incapable of working hard. When I was 13, I took the initiative and got a job doing computer repair. I worked hard at work, and hard at home expanding my knowledge. While I wasn't the most knowledgeable guy at the office, I was certainly not the least. Now, 2+ years later, I'm making a good bit more in an office than I was when I started working, and I make good money doing freelance/independent computer repair/training, etc. When you're 15, $35-50 (depending on the customer) is pretty good money, seeing as I don't have a ton of overhead, aside from geek stuff. I get a nice tax refund too, because I don't work enough for it to be qualified as full time, year round.
The point of this story is that I feel for the OP, and I completely understand why he didn't originally post his age. Setting aside his business plan for a moment, how many of you would honestly think about doing a project for pay for a 13 year old? Had his posts and business plan been more together, he might have gotten a better response.
To the OP- in theory, and application like that would be a godsend for the masses; it would help people with little or no coding knowledge be extremely productive. In practice, though, it doesn't seem feasible. The sheer coding knowledge to do something like that would be rare. As other have said, you'd need to program for an extremely large number of actions. This has been tried by, and I mean no disrespect by this, people and companies with more resources and coding talent than you have at your disposal, and hasn't really caught on in the general population. Automator is looking to change that, but whether that will work remains to be seen.
I'll wrap this up now. virus1, don't get too discouraged. You had a good idea, but it just isn't feasible. Continue your learning and continue to further your knowledge, though. You never know what opportunities may present themselves if you are knowledgeable.
