MC Helicopter Mod (FML)
On http://workingwithjava.webs.com/ you can see coding that I have done in java for school giving me the idea of making a server. If you scroll down to the bottom of the homepage you can see the time and days when the server is open (during school months). During summer vacation it will be open almost always 24/7.
The server requires Forge Mod Loader 1.7.10 and MC Helicopter Mod (you can see what I mean if you try to go on the server before making sure you have these two things)
