Custom sized RGB LED Matrix, where can I get one?

I am needing a couple of custom sized RGB LED Matrix displays for a project of mine. I need two different sizes.
The display screen on the first one needs to be 9"Wide x 3/4" high. The display screen on the second one needs to be 11-3/4" Wide x 3/4" high. They need to be color displays. Does anyone know where I can get these like the picture I have attached but of the custom size I need? Thanks in advance.

Custom size? Unfortunately not. Many customers simply use “building blocks” of 8x8 matrices which can be found here in different sizes:
