Handpicking can be very effective if done thoroughly on a regular basis. At first you should look for snails and slugs daily, paying careful attention to potential hiding places. After the population has noticeably declined, a weekly handpicking can be sufficient. Prior to shipping, all plants should be inspected and any snails and slugs must be removed.
