Neji didn't like the donation center very much so I am going to add some spices into it.
Donation Center
"Welcome, this is a donation center built under the 5th Hokage, Tsunade-sama's order to collect gold from you rich- I mean kind-hearted ninjas to help her pay her debt- I mean to raise fund to help those who are suffering because of Orochimaru's rain of terror and from the aftermath of war."
Features
1) You may donate any amount of gold as you wish.
2) Your donation will be recorded.
3) There will be a list of donors, sorted by the highest total to the least.
4) The total sum of donations from all players will be displayed on the top of the donation center main page.
5) Once a player's donation reaches 1 million gold, Tsunade-sama will pay him a personal visit.
Monument
Tsunade offers you a chance to have your face carved on one of the mountains overlooking Konoha Gakure.
Features
1) You will have to 1st buy a spot on a mountain, which cost 10 million gold.
2) When you finally bought yourself a spot, you will have to pay for carving job, which cost 1 million gold.
3) Once it's done, your monument will be displayed in Konoha Gakure for all eternity (or until Neji decides to close the server).
