Create Artwork on a Light Box

I'm looking for a simple graphic design to be applied onto a light box (picture below)
I have made a mock to give you an idea (see attached)
QR codes to be added for facebook and instagram. Can send social media links across.

My logo - Triangular icon is my logo to be placed on the artwork. It can remain in its original colour but can also be played around with.

The artwork needs to fit into these dimensions
750mm wide x 200mm deep x 400mm high

Thank you.
