Excel postcodes to long & lat via Google Maps API

Hi, I have a spreadsheet of 100k addresses containing UK postcodes. I require these to be populated with long/lat data as per: [login to view URL] Each address needs a call to google and the resultant long lat adding to the listing. I can supply the file in Excel but I guess it needs pulling into mysql and a simple javascript or plain php call to google's api to iterate through every record recording the returned details. An example of the xls file is attached [ I will ensure the postcodes sit in a field on their own inthe actual file]. I could do this myself but haven't got the time this week, it hink it's an hours work topsds to write the script. Budget is $30 only!!!!!! Any q's let me know.
