I'm so sorry about your mom!  
 
I would take them if I was home all day but my husband is the one home and he could never handle 4. 
  
We LOVE our vet and they do overnight care.  They are just west of Aurora.  Orchard Road Animal Hospital.  I also know a great pet sitter in Batavia but she has big dogs....  
Isn't anyone closer?  We seem to have a lack of Chicago people on the board.
