sign designer block....

[nashvillesigns]

Hello!
So i am doing this project and have discovered a "what to make this out of" block.
sigh.
the artwork is to be 36"x30 wide. it is going to be mounted on a office meeting room wall. it will have have three logos.
1. the city town seal logo in the background.
2. 3 municipal logos "surrounding it". these logos are smaller than the one mentioned above.

i am looking for a way to have all this combined. i am doing a mock up with foam board. a base plate with 1.
a second layer with all three logos mounted on top

suggestions on how i could create this??
i am not printing this on viynl and slapping it on white aluminum, if you get my drift, here.
i am thinking between full blown carved and that. personally, i don't think they would pay for bronze.
(below is the artwork style. this is NOT the final artwork, do not taze me about that.)
thank you for your input and praise.

Gemini does the the etched plaques that might look nice. maybe do a mixed metal, layered piece
