Can anyone recommend an affordable bunny vet in the Dallas, TX area?

My 9 year old lop has had arthritis trouble for the past year or so, but he recently acquired what appears to be Floppy Bunny Syndrome and has had a difficult time standing up on his own. His usual vet is closed tomorrow and I need to get him into an exotics-capable vet that can administer fluids and help treat him. We're in the Dallas area, so any suggestions for a good (and hopefully affordable) vet nearby would be greatly appreciated.
