Make small chnages to mysql database.

We have a fairly simple database for a language school. We need someone to make some small changes so that one function is disabled if another is activated. Also we need to alter the 'late cancellation' function, so that the lesson is removed from the teachers schedule when a lesson is canceled late, but all the remaining function still work. Also we need the 'students' to be listed alphabetically, and some small changes to the colours used. For anyone very familiar with mysql this would be a very easy job, so please only reply if you have expert knowledge of such databases.
