Server Buying

Hello,
I would like to know if it's possible to rent a server.I love all the features that Aternos provides however it would be awesome ,if possible, to have a server with limited slots (paying for it of course) so it keeps running even not full.

Thanks for the time, "Stoolker"

P.s.:I'm Newbie ate english

I understand,in fact ,it's that concept that leads me to the idea of renting in Aternos.
The other rental server providers don't give the chance to test,thing that Aternos gives because it's for free,which for me is important in terms of trusting.

(Anyway, this was just my thoughts and ideas. I don't want to question your job)

Thanks for the time, again, "Stoolker"
