I'm sure that Lynn will be happy to hold your animals for you until you get everything worked out, and everyone there healthy. I would have no problems holding an animal if one of my customers contacted me and needed me to hold their animals a little longer.
I answered in your other thread - keep the humidity UP (helps break up mucus), which may be challenging now with the heat lamps, keep a hot spot about 95 degrees, and make sure his enclosure is away from any drafts.
The fact that he's rubbing his face (especially if you see slime being left behind) sounds like it's an advanced case of RI. You may indeed need to treat the other three that were housed with him, since they shared the same water dish with him.
Have the vet do a culture (may be more expensive) by doing a swab, but it will help the vet determine the right medication to prescribe.
In the meantime, listen to this episode of Reptile Radio - it has a lot of good information from the leading herp vet in the country (some would argue in the world), Dr. Scott Stahl, and he specifically addresses RI's and the protocol for treating them and why getting a swab is so important to determining which medication will be most effective. I also believe it will help you be a better armed to ask your vet the right questions when you take him in on Monday.
It's a long episode, but I've listened to it many times, even MY vet has listened to it when I recommended it to him.
