Kill counter + save to database + leaderboard!

Hey guys i’m looking for a kill counter script .
-> when you kill a player , it saves the kill to the database “kills column” in “users” table and adds to the rest of the kills and he can view his kills ingame with a menu or button or any ui idk + a leaderboard to view the top 10 highest kills players .
-> tried to make it and spent a week working on it but it i only got close results and couldn’t get further .
-> willing to pay whetever it takes for this script .
