Adjust mySql table

This is a simple job, will only take one hour at most. Experienced database engineers need apply. You must be well-versed in: mySQL version 4 phpMyAdmin - 2.9 (is a benefit) Speak and write English is a must. I am looking for someone to make minor additions to my sql database by adding extra fields to a few of the tables. There must be NO ERRORS in order to receive payment, that means I will not pay for an incomplete job. Money will be in escrow intil the job is complete.
