Sublime187: If I know you will play I will give you free passes .
My two Pfennig:
Don't do that!
1) Pass purchase is a waste IMHO,
2) With that, you block their free passes, and these would perfectly do for the development of your new CC. At L4, you get the second "Pal", the last benefit of any commercial value. Let your CC grow naturally then!
3) If you have credits to share, gift your members balls and/or clubs. This, and some common activites like tournaments and other competitions and activities, will give them fun in the game, and they will happily use their free passes to support their beloved CC.
Announce some fun and communication - e.g. voice talk via Skype or TeamSpeak, and encourage your mates to their own initiative - it will be a great place to be!
Good luck!!
