Florence City (Roblox Game)

I am looking to develop a Roblox game called "Florence City" and I need some assistance with game development. I have already set up the game, but I require help with creating in-game rewards. I am open to any ideas or suggestions for rewards you might have. I am committed to quality and want to ensure that the game is one that people will enjoy. I have taken coding classes before but I am unfamiliar with Lua script so I need some help. It would also help tremendously if you are good at normal Lua script in general as I'm very bad at making scripts that will actually work, I have big plans for this game and I would be glad to give a percentage of the proceedings the game makes to you for your help!
