While we are more than willing to help those that are stuck, that doesn't mean that we are here to do it all for you! We can't do all the work, you are either getting paid for this, or it's part of your grades and it wouldn't be at all fair for us to do it all for you.
And there are problems here that you need to think about: you are asking strangers to write code fro you top make you money: "one big coin" implies that you expect this to make to a fortune. So ... why would anyone else invest a huge chunk of effort to make you rich, rather than them? Personally, I'd view with some scepticism anyone who offered to do it for you: if you don't know what you are doing, they could more easily empty your account - that they will need access to to - and disappear with all your existing money. And you may not even notice until it's too late.
There is no shortcut to getting rich: it always involves effort.
If you seriously want to do this, you need to learn how. And that means learning how to be a coder first, and building up your own experience until you are competent enough to do the work!
