Urgent help needed - Where can I get acceptable Canada passport photos done in the US?

Serious replies only please, the next stage of my new life depends on it.

I'm at a loss here. I have 7 days to turn in acceptable 'physical' Canada passport photos or my CoPR will be cancelled. I haven't gone through all these hoops just to fail at the end and unfortunately I've had my passport photos rejected twice.

This last time I had them done at Walgreens and the first time they were taken at Riteaid. Both have been rejected and a yellow highlight has been shown on 'Must be taken by a commercial photographer'.

Where can I go in the US to get acceptable Canada passport photos for my CoPR that will be accepted? I don't have another chance at this point.
