Cardboard display stands wanted Italy

We are looking for a FLOOR DISPLAY STAND in CARDBOARD and suitable for A4 DEPLIANTS.

Of course the product must be full colour print and we would like the top with 2D shape (most likely a vessel)

We would like the offer both for a single layer (display tray) and multi trays.

Here attached a couple of concepts our client likes and some concepts we found on the internet, but we are open of course to other ideas based on your expertise.

In terms of quantities, pls advise the max. possible quantity for a total budget of Euro 20.000
