If they are not involved already, get them to play club soccer in the fall at any level available to them. Get something on the website at any local clubs you have and have their team managers spread the word. (Sorry I'm not sure where you are)
Get a flyer out NOW to the middle school and freshman so they can be involved in May tryouts. Start getting fit NOW. January is really too late to start. The top teams have players that play soccer all year long and show up in January already fit for the most part. Good luck!
