Odd shaped PCB possible? (and what minimum thickness of PCB)

I’d like to get some small PCBs made up but the small PCB I require needs to be rectangular (about 55mm long by 10mm wide) but with the corners rounded slightly (don’t ask!).

Therefore are none straight edge PCBs possible with Batch PCB? (is so, how do I actually present this when ordering?)

Also what minimum thickness of PCBs are available? (0.2mm, 0.4mm, 0.6mm etc?)

thanks,

Pesky.

I don’t know about thicknesses, but I do order round edge boards from batchpcb.

Edit:

You can draw the outer dimension to the copper layer. Or use a combination of the dimension layer and a ground plane (what I do).
