Uhm. Don’t you already have a Pointshop? If not: http://www.facepunch.com/threads/1022682-WIP-
The above pointshop gives you points (you can set the amount) for each kill you get and each death.
And for the other thing about the traitor or detective thing. Do you mean they can use their ingame credits for buying like a knife or health station for Pointshop money?
If that is correct, then all you have to do is go into the items.lua for the pointshop and add a new tab and then add your items such as 1 credit for 30 points or 50 points for 1 credit. To do that you can just make the OnGive function set the players points to his current amount + 30 points then do the same to remove a traitor/detective credit (You would have to find the code for giving points). Or current amount - 50 points then give the player a traitor/detective credit.
I think you should hire a lua coder untill you get better at coding to do it yourself (do random small projects to increase experience and skill) rather than constantly asking for someone to make you a code for free. You can pay one person to make it all on your demand with a faster response than facepunch.
