MYSQL and PHP project -- small n simple

A simple little project. 1) I need someone to set up a small mysql data base (one field) and allow values to be taken randomly. Also has a user field to allow users to add data to the data base. I require this to be done twice onto different sites, using two different sets of data. 2) I need a data base with two fields (a , b), source from two text fies. To take a line at random from a + b (ie line 56) and display a on page, when button is pressed on page, line b is revealed. Also a user field on page to add data to a and b. (with error checking no value less than 6 chars or greater than 150 chars in either, both fields must have an entry.) Thanks
