Weekends no matter how hard you work will still take considerable time. Instructor rating approaching military standard? Only place you will get that is in the RAAF. If you and your partner are going to the QLD champs this weekend there are a few people you can talk to about this. Granted there aren't many quality providers these days, due mainly, to do it properly costs serious coin & serious coin students will not pay.
A good mate of mine who runs a pretty good school is thinking of tossing the instructor ratings in, doesn't pay anymore.
