In the way of trainers vMenu comes with the most amount of features(to my knowledge since i use it lol) and a permission system that is very easy to set up. Im not sure if this helps you but you should try it out.
However i know you can edit PEDS and change various of other options.
And since this is server side you do not have to have scripthooks on.
There are not a whole lot of server sided trainers out there so Good Luck!
