Vehicle shop system HELP!

[=VG= .Blizzard.]

I need a vehicle shop system, something like SVSS https://forums.bohemia.net/forums/topic/188119-release-simple-vehicle-shop-system/

I tried it but It won`t work properly with my mission. 

Have you guys got something similar or can you help me implement this somehow? 

What we need: - some vehicles need to be free 

                            - kill bots to get points/money 

                            - vehicle spawn point on a helipad/marker

                            - multiplayer compatible. 

Pls help me mumsy!
