1. The server needs to be online when I am.
Of course I want to be able to play on my own server!
2. I should be able to make changes to the script and restart the server to implement them frequently.
I edit the script (and map and stuff) a lot and sometimes I need to restart a lot for debugging.
3. It should be reliable and as cheap as possible.
I don't really want to pay (a lot)... - And of course it should be reliable. I need trust you, I don't want another corrupted PC/phishing/whatever.
4. It should be able to handle at least 8 players at 1000 ping (that's pretty much what it is able to now) or more/better.
That's the whole point of it, isn't it?

1. It should be online as long as possible.
The longer the better, it means I could get more players when I am online.
2. It should be as cheap as possible.
Bonus points for cheapness. But I could trust you less.
3. It should be able to handle as much players at ping 1000 as possible.
More players, more fun.
4. If it can handle 32 players, it should handle the best ping possible.
This allows even more players in.
