One option is to find somewhere reasonably local who’ll sell a standard gaming mat (eg 4’ x 4’) and cut it up. Alternatively sign printing companies might be able to print something onto vinyl for you. Or anywhere that makes branded merchandise.
I’m in the UK so I can’t help with specific suggestions I’m afraid.
I guess my first instinct would be that that's a good use for that one fold-up board you have that's falling apart - replace it and cut it up neatly into its 8 little sections, and use those as terrain bases?
Feel free to call me Dave!
