Second opinion on the time it would take to correct an issue with a database - repost


We have a school database for a charity organization event. Schools are entered into the an administration panel of our system and then teachers are sent a code to login the portion of our site where they are able to register students, pick a lunch for each student and add the amount of wristbands they would like to have shipped to their school for fundraising purposes. At this present time having multiple schools registered under the same email causes an administrator with multiple schools to only be able to login to one school account.
