Gmod Team system

I am looking for a Team system for my GmodZ server, What is does is basically it will add a little blue circle or something noticeable on a teams body and will disable friendly fire.
I kinda want it to were it will have a small box with the name of the players on your team in the top right hand corner and allows their to be a team leader, And the team leader can kick players any can invite them.
Only the team leader has control of inviting and kicking.

If anyone can make this for me I will be willing to pay.
