WORDPRESS=$1
SITENAME=$2

CURRENT=$(pwd)
NOW=$(date +"%Y-%m-%d_%H%M%S")

mkdir -p "${BACKUP}/${SITENAME}"

echo -e "${YELLOW}Backing up the database...${RESET}"

wp db export "${BACKUP}/${SITENAME}/dump.sql"

echo -e "${YELLOW}Creating the archive...${RESET}"

cd "${BACKUP}"
zip -q -r "${ARCHIVE}" "${SITENAME}"

echo -e "${YELLOW}Uploading to Dropbox...${RESET}"

cd "${CURRENT}"
./dropbox_uploader.sh mkdir ${SITENAME}
./dropbox_uploader.sh upload "${BACKUP}/${ARCHIVE}" "${SITENAME}/${ARCHIVE}"

rm "${BACKUP}/${ARCHIVE}"

echo -e "${GREEN}Done.${RESET}"

I'm not using WP-CLI's --path option because it doesn't appear to work well with subdirectory installs.
