Might be taking in an iggy for rehab...any advice?

[Squirgle]

I work at a pet store, and some fellow employee thought it would be a smart idea to accept two malnurished iguana's from a customer. One of them isn't so bad and thus we will be able to take care of it in the store, but the other one is a bit worse. Very skinny, the base of his tail is almost all bone and sometimes rather lethargic, he is going to need more work than that. One fellow employee wanted to put him down (even though we don't do that) and I wasn't about to let that happen so I offered to take him in for rehab before bringing him back to the store. He is about two foot from nose to base of tail so he has been around for a while. Now I may not know everything about iguanas but I know all the basics. I know what to feed them and basic requirements of the such but I was wondering if someone could give me some advice with rehabilitating the guy. Any Do's or Don'ts of malnurished lizards or pointers with doing this? I'd appreciate it.

P.S. I'm still not possitive I'll be getting it, this is a 'just in case' sort of thing.

Read thiswhole site and print out what ya need to keep, like the food section.
The Basking Spot.

Other than that, feed in the morn, plenty of UV lighting and use calcium supplements on the food for a while on both of them as they may have MBD in early to mid stages by now.

Plenty of water to drink and you may want to mix it 50/50 with pedialyte for them.
Mist them also to help with any shed probs they may have and keep them in a well ventilated set up.
