312153 osCommerce Missing orders

I run a small website using osCommerce. I asked a programmer to delete all order records from 2008, He done this, however orders from Jan-Apr09 have gone and the orders from 2008 are there. I have checked, and the orders are still in the database, so they are recoverable. I need you to delete all records of orders from 2008 and restore the Jan-Apr09 orders. There are also two products which appear on the main page, which I cannot remove. Look forward to receiving applicants, coder will be hired today! Best Regards, Job shouldn't be too difficult for someone who knows how.
