Large 7 character 7 segment display with LEDs

I’m thinking of building a large display. 7 characters in total, with 7 segments each, and 4 LEDs per segment for my initial design. I need to power 200ish LEDs and control 49 separate segments. (Powered externally)

Does anyone have suggestions on what board would be convenient to use? I’m thinking of using three 4 to 16 MUXs.soo I’ll need at least 12 outputs. I’d like the total project to stay under $100 as well.

Sadly I’m only familiar with my Arduino Uno, but I’d like to branch out.

Any suggestions?
