OK here are two options. I'm in Canada, so any $ mentioned is CDN money. Just so ya know... here we go.
1) the fogger way:
I got two juice containers (like used for the welches juices) that are about 2L. Cut the top half off of one, and the bottom half off of the other. The one that is beheaded is used for the main part. The bottom of the other one is used for the lid. Usually the bases are wider than the middles, so if done right it should fit right over top (oooohhhh aaaaahhhh lol). Cut a small hole in the lid for the chord to come out. Cut little slits across one side of the main part. This is where the fog will come out. You don't want crix or chams to get in there, AND the fogger spits up a little water. It will hit the lid this way rather than go all over your cage (aha!). I have about 3 slits in mine. It doesn't take much. Figure out how deep you can fill the water for your fogger to work. Put it in your snazzy new dish thingy, fill with some water, plug it in and keep on filling till you either come close to a slit, or it stops working (they only work well up to a certain depth). I have little glass marbles in the bottom of mine for weight/stability, and they are pretty *such a girl* lol. With the lid on and the water in (oh it will automatically stop when the water is too low btw) it should be stable enough that your cham can walk on it w/o tipping it over. I find that using the juice jugs is perfect because they are wide enough that with the right depth of water it still works AND there is enough water to last a 24 hour cycle (genius!). There you go. you can play with the timer to see how often you need it on forhow humid you want it.
You will want one for each cage. They produce enough fog for one cage, but I don't see it being enough for two. They are about $40 each, and the juice jugs are not much, so it isn't a lot. Also, I have mine on a shelf near the top of her cage. The fog will just flow down, so you want the fogger up high. I'm not sure how your cage is set up... you may have to just put in on top if there is room, and the fog will flow down though the screen. ALSO I have a beach sarong that is ankle lenght that i use on that side where the fogger is. It keeps the fog flowing downward IN the cage, rather than all over my room (more genius!). I use another one to cover her door, so she can't see my cats.
Ps if the fogger stops working just use a q-tip and rub the top that looks like a coin. If that doesn't help you can take it apart and clean with vinegar. It'll work like new. They want you to buy a new filter (the coin thingy) but cleaning works just as well, and no stores actually sell the filters so you ahve to send away (ha!) Can you tell im in a chatty mood?lmao
Option two: Use a warm mist humdifier. Mine was about $60-70 I just use it in winter cuz it gets terribly dry in my house (about 20-30% eek). I have metal air ducting thingys (a base and an elbow) to aim the mist in the cage. Works well. I have it on a timer also. You could get different ducting, and work something out so that there are two places the air is directed in. I haven't tried it, but I think it would work. You have to clean this a lot. It's gross (that's why I ONLY use it when I have to -the winter, lol). YOu have to empty the base and wipe every day, and once a week clean with bleach and water. And you ahve to fill it every day, if used a lot. And it will make the whole room humid. They can be great, but only in very dry situations. I find I keep the humidity in my room about 50% (which I like) and then let the fogger do the rest.
Well, there's my two cents (or about ten lol)

I think two foggers is your best bet
