aggree with @Dastgir but you can do this also
1. Learn how to use basic GIT (All file changes tracked, never ever direct edit on your VPS)
2. Hire Developer/scripter or whatever you need to build a great server.
3. Hire Secret Agent (whos understand what the Point 2 does WITHOUT telling them #3 is exist LOL)
4. This one is optional Hire another Secret Agent to track Point 3 in case if point 3 make some evil cooperation with some of point 2.
5. Enjoy~
