Manhole/Access Cover Illustration

Hope this message finds you well!

I am looking for a graphic designer to create an illustration.

We sell manhole covers/access chambers and we need a graphic to describe to people how the measurements work.

There is a "clear opening", "overall frame size / external dimensions" and "intray depth".

There is 2 versions that are required, themed off the two websites we'll be putting the image on.

EcoTradeCounter.co.uk
RecessedManholeCovers.co.uk

I shall attach a current basic old version we have that needs redesigning/reimagining.

Kindly let me know your thoughts, please.
