I thought that header might get your attention

I have two large sheets of metal that I need cutting/drilling/riveting together and screwing into a window frame to make it more secure.
The window already has bars/glass break etc but I'm just going for the overkill.
Fitting to the frame will likely be with security screws (have those) and can pretty much be done anytime (soon).
No tools supplied.
Anybody here want/able to do it, I imagine it'll be about 1-2 hours work
Window is in New Ferry attached to a building, so you will have to come to it.
