Shooting game Roblox

I am making a Roblox shooting game, so far it looks great, but I need some help with making round systems and gamepasses. If you could I would love if you could make me a game trailer to! I will be open to paying you based on your actions… (I’m sorry but I don’t got a lot of money so it might not be a lot) If you can DM me and if not I will DM you.
