If this server will only be used for certain special events, it will fail for sure.
I dont believe anyone wants to pay this amount of money to play on a server 2-3 hours a week.
one hour ago we were 7 people online where 6 of them were Smokers, i encourage them to come online whenever they have time, but i will loose them soon if nobody else starts playing on the server, especially at prime times EU 17.00 - 22.00.
