I would be most grateful for any advice on how one might contract for production of the type of corrugated custom plastic board signs for advertising property rental or land sale. I'm talking about small ones, less than a square meter in size, presumably produced by laser printing from some kind of vector based artwork. I am in Bangkok Sukhumvit.
These things are everywhere these days but I have yet to find anyone who knows where to get them done.
Thanks much for any advice on sourcing.
