Hello, I can surely help you with your family project. However the price range is a little bit low considering all the features you want added.
Maybe, and if you don't want to start spending so much upfront, we could redefine the project with less functionality, and give it a go. Later we can start adding new features for a fixed price each.
I guess the site won't manage money, I understood that will be managed privately by your family, is that correct?
It's not clear to me how will the group betting work to be able have 1st, 2nd and 3rd places. I envision the group bet as an statement and a fixed amount, like "Lakers vs Knicks" where each participant choose a winner and the amount is fixed, then the winner group splits the amount the looser group bet.
So please explain to me how do you picture it,cause I don't see a way to have 2nd and 3rd place in that scenario.
Also, I guess that you'll want this site prevent anyone from signing up, since it will be private, right?
Let's talk more about what you want to accomplish and let's define the project better, so we can agree on a proper price that works for both of us. Also, consider what I've said at the beginning: we can start small, with basic functionality and add new features later.
Thank you
