Petsmart is a great way to look. Instead of heading to all the ones in your area you can just call them and ask if they have "orange and white" Midas or Red Devils. I'd say 10% of the Petsmarts within easy driving distance from me have that type in stock at any given time.
Another possibility (albeit more expensive) is Rapps like others have said. He tends to stock Amphilophus xiloaensis which is orange and white. Not Midas per se, but pretty darn close.
Best of luck!
Edit: Darthodo, where are you in Georgia? I'm in eastern Alabama and have a 4.5" female creamsicle for sale. I'm looking for a good home for her, she's awesome but I just want a male.
