No amount or duration is enough. the technology is too broad and evolving. The more you study, the more you realize how much more things you need to know. If you have a solid proposal, I suggest you open a thread in marketplace section. There are many skillful and talented individuals here on the forum. You will have to find the best among them for the project. I wish you all the best. I also have a project which I personally intend to fund but I am looking forward to recruiting people offline.
