I agree with Trish's version and may be a thank you at the end?

I've got a note too on the front window which is next to the door.

I am a lot ruder than you two are though

It says :
Absolutely NO door to door sellers and/or hawkers.
You will be reported.
Thank you.

I hate it though when they come calling at night and the front light isn't on.
Dh says i should invest in some neon lights.

I'm much ruder to them at night
