316L stainless steel perforated sheet

I am constructing a one-off working prototype and require the following:

Material type: 316L stainless steel (negotiable if too expensive, or not flexible enough)

Number of pieces: 35 --> 29 of one type and 6 of the other

First type (29 pieces): 170mm x 135mm x 0.5mm (length x width x thickness)

Second type (6 pieces): 525mm x 135mm x 0.5mm (length x width x thickness)

The second type of S/S sheet MUST be perfectly bent in a U-shape over 3mm thick acrylic sheet, so it will be a perfect fit when I slot it over the acrylic sheet I already have. This is shown in the attached jpeg file

I would like all the stainless steel pieces cleaned and wrapped up for delivery
