Large lidded bucket any colour but not clear (Fazakerley L11)

Hello I'm looking for a large lidded bucket to make 'weed tea' plant food out of garden weeds in the church garden. We are trying to be more eco friendly. We've made a leaf mould cage already helped by a freegler who provided the wire. The bucket will be for Christ Church Norris Green but I'll be collecting it as an individual. Thanks for your help.
