It sounds like pancake has had it little rough from your other posts, how is she doing?
You can make a temporary setup with a large Rubbermaid tub while you are gathering equipment for a second set up.
You can get a large, tall tub, inexpensive dome reflector and bulb for heat, and a UVB fixture for probably 30-40$ if you look around. The you just need the
UVB bulb. If you can find a big enough tub you can divide it and put the UVB across the decide so both sides get some (assuming you have a long florescent tube.) If you don't have other pets, or can put them in a safe room you won't need to devise a lid.
If you can't or don't expect to be able to provide complete setups for the two of them, if may be in both of their best interests to consider rehoming one of them.
