Convert cgi guestbook script to php/mysql and paginate

I have a guestbook with over 700 entries It is stored in a mysql database and is currently run via a cgi script The admin has broken down and does not enable me to edit existing entries. My tech staff think there are too many entries for the cgi script to be able to cope with...which results in an internal server error So...I would like a guestbook designing where :- customers can place comments admin can edit those for typo's etc admin can search for an entry easily to edit it viewer gets paginated pages It would be VERY important that the existing 700+ entries can be pasted into the new design. Its an easy project for a competent person so please...no big bids Budget of $70 is a fair price for this.
