Not sure why you might think a bay shaped awning is appropriate over top your entrance.

You could have any of the metal awning you see below for your home.

You don't hire a handyman for this job and expect a successful installation. This should be fabricated and installed by a metal roofing contractor so the awning, once installed, is appropriately attached to the face of the brick with no water leaks.

Your entrance requires a better walkway to the front door.
