Serenity, Gteetings to you.
I used buckets last 3 years and they were very successful. You can buy the buckets in B and Q for 98p( good value). Drill 3 or 4 holes holes in the side of the bucket about 1 or 2 inches from the bottom
and you've got a little well of damp compost at the bottom of the bucket. About 3 spuds would be great. Good luck.
Cheers
Tomas.
