If you can't order one from a home brew shop, or an online homebrew shop, then scald the bucket with boiling water. Scrub it good with a soft sponge and some dish soap, scald it again, and then let it sit overnight with some star san sanitzer in it before you use it to do your primary.
Still, I'd boost the coin and go on line to order a bucket designed for that purpose.
Cheers,
