coupe rust repair section

[racefast81]

Hi All
There was a guy a few weeks back advertising on gumtree a left and right repair sections that were for left and right side of boot lid that also went down to above the rear bumper following the beaver panel ( as you can tell I have no idea what to call this part)
Does anyone know who this person is and how to contact? or know of someone else making this section?
I have attached a photo of the section I am looking for as this is probably the best way to describe the section, you can see mine has hade a repair( a very rough repair) some time in its life
Many thanks
Brad
