I think your initial plan of action sounds pretty solid to me. Though I will agree with Gladius as well, if I am understanding correctly what he was saying, but it is possible that a bi-weekly setup at first could be confusing to non regular players. I mean I am sure you would post something on the NPC Server message so you would think it would get read leading up to the Saturday so someone that logs on should know if it is the coming Saturday or not. I mean this of course is the growing pains of getting it going initially, but I think it sounds good. I myself would then make sure I am on on those evenings whenever I am not having to work.
I will also say that the events I have played on there so far are extremely fun if not addicting at certain points.
