Bricks to make a garden border (Tottenham N18)

Hello folks, I want to create a small garden border with bricks to separate it from the lawn. If anyone has spare bricks to donate I'd be grateful.

I'll need ~20-30 bricks. I can build it a little at a time if you have fewer than this though :) The closer to N18 near North Mids hospital the better, but can/ will travel further afield if need be. Thanks so much!!
