Your chances are very very small of success. Most developers I know, and all the *good* developers I've known over the years, have a passion for writing code. When they're learning, they are coding 24x7, sticking their nose in every corner of a language to figure out all the details. They treat their code as art, it is something to appreciate, come back and make adjustments for visual and performance reasons; something to enjoy.
By comparison, your proposal here has no passion, it describes a process of rote memorization to replace what should be artistic creation; a trade off of quantity over quality. You've been registered on this site for seven years, had seven posts, and still can say "... I don't know enough to write code from scratch" - to me that means you don't have the aptitude or interest to actually do it.
Sorry for being blunt, it's just how I see it from what you've posted. Hopefully I'm wrong and you can come back in a year and tell us it's been a huge success.
