2,500 overcaps for 4 oz continuous spray metal

I need an overcap that runs flush to the side of the can like the picture attached.
I am not exactly sure of the measurements but I have a 4 oz continuous spray metal can with no ridge. that minus the top is approximately 4.5 inches high and I think 52 mm in diameter.
As we are keeping the existing top on it, it needs to be single shell and there is no ridge so the top needs to just fit over the can.
I would like it to be ideally in Silver Metal or some sort of buffed silver finish (see attached) but a plain white (matte or gloss) or plain black (matte or gloss).
The top can be domed as long as it is about 5 cm tall. I need samples of all colors/sizes to make sure it works as we will just be putting the overcap over the existing cap.
I am looking for around 2500 to start.
I am looking for an existing overcap so that I can get it as soon as possible.
