Sorry bro but, nobody is going to give you a free server.
Seeing as you just listed a bunch of minigames and you apparently have no actual game ideas yourself........ that makes you even less attractive. Even if you have the best game idea in the world, I can almost guarantee you will not get a free server unless you are a YouTuber with 5000+ subs.
You also listed some minigames that I haven't heard of, and things like "Custom Perks, Weapons, Ranks). This makes you sound kind-of original, but you didn't go into any detail about said games. This shows you don't even put in the effort to make a presentable thread for "your" ideas. Also, you saying "And Much More" makes you sound like you want people to think you have other ideas. My opinion on saying "Much More" or "etc" is; Its either important enough to put in the actual list, or it isn't important, so we didn't need it (Much More/etc) in the first place. The only place where this is acceptable is if you have any sort of time/space constriction, where saying that would be understandable.
Additionally, I don't understand your logic. Lets just assume you get donations for this server (not going to make any bets here) just for this example. You said you will pay for the server, get staff, and pay for the website. After doing all that, you're still going to pay said server host 50% of the donations. After you've already paid them for the server........... Like what?
Additionally, you provide no detail for the type of server you want, or the specs of this server, or if you want multicraft or whatever else. If I was a company, I'd be like, "Sure, I'll let you have your fun, enjoy this 128 MB server. Have Fun!"
All this stuff you've been saying seems like this is just a silly flippant wishlist, which, if it is, I shouldn't be crashing it so hard. However, when you're dealing with real companies and real money, especially in what you're asking for, which is an investment. (Yeah, that's what you're asking for). When you ask for an investment in this flippant, unprofessional way, it isn't something that will be considered.
Sorry for crashing down of this as hard as I did (with a fair amount of rudeness), but you should understand what you're asking for here, and how serious it actually is.
Also as for the tl;dr or "Nice Book" I prefer to employ the TL?DR method or Too Long? Don't Reply.
