Make it Rain!

Make it Rain! by ryancpexpert!
What is it?
Make it rain is a mini-game I have created that takes the concept of the ios app, make it rain, and puts it in minecraft. With just as much pointless-ness as the game, cookie clicker, this game is a VERY addictive game. I have recreated the game in minecraft to the best of my abilities, and is still in WIP stage. Currently, you can make it rain only $1 bills, but in the future, I plan to add in investments, I already have the shop setup, just need to add the investments.
What is the objective?
To make it rain! There is really no objective, similar to cookie clicker, which makes the game just so addictive.

I currently need help with the investment prices, as I have already progressed so far in the app itself, so if anyone could provide the prices for the investments, it would be most appreciated!
