I assume by "after my ow" you mean you're wrapping up certification? If so, I highly recommend one of two options:
1. Hire a pro. Certification doesn't make anyone qualified to dive safely with other novice divers with few exceptions. There are some that REALLY know their limits while others are so used to having the instructor they forget the risks, pre-dive routines, signals, etc.
2. Join a dive club and hook up with much more experienced divers. There, you'll find rescue divers, dive masters and even instructors that will dive with you.
As for the 24th, if you can't find a much more experienced diver on here for that particular day, go with option #1.
Good luck and be safe!!
