You're basing your plan on a 10% per month return, which is wildly optimistic. A 10% monthly return correlates to a 185% annualized return. A 20% monthly return, which you also suggest, comes out to over 640% annualized.
No day trader will make these numbers on a consistent basis. Over the long term the market will yield a return that's in the high single digits. Even if a day trader is able to double or triple this you don't get close to your numbers. And even that is optimistic; even good day traders will lose money some years.
You'll need a lot more capital and a lot more patience than your calculations indicate.
