Small PHP Job - importing into MySQL database

We have a script that imports a large number of items from xml files into a MySQL database. It is supposed to run on a cron job every night to update the database, but the import seems to stop before all the items have been imported. This bid is for fixing it so that all the items from all the specified files are imported successfully. (I don't know whether something needs to be changed in the script, or in the database settings or in the server settings - I hope that will be easy for you to see!) The lowest bid amount I can choose is $100 or less - I haven't set a maximum, but I should tell you that I hope to get this done for a lot less than $100! I have put a 2 day deadline but you'll need to start right away as the files take a long time to import. Let me know if you want to work on this but would need more time.
