Simple Search engine of items for Sale

Hello! Need help writing a simple search engine and a CRON job to monitor and summarize a database of items for sale. The program must look for all items added to a MySQL table, and for each item store related keywords in a summary table along with a score. The search piece then simply query through these keywords to retrieve items. Not a long project, 8 hours max for a good PHP programmer, but need somebody with good knowledge of MySQL and capable of reading a detailed specification document in plain English (I have a 3 pages document that describes in detail what needs to be done. I am always available for questions obviously). You will be asked to install the script on our staging server (you’ll have an FTP account), using an HTML template provided for the search & search result page. There will be several more projects related to this one for the successful provider.
