getting free admin for a week,or month

ya i like how you are doing a monthly prizes but it should be for free. Like u get admin for a month or week for winning a drawing
i know u need money for the server, so if they get admin for free they will have the experience of being admin. Then they might buy admin since they liked it.. so your'll get more money this way. and if they are admin abusing it is easy to just take them off of using admin.
