Database change fields on xcel spreadsheet

I have a list of 6500 addresses that I need to have some information changed. I need the address field to be broken down into address, suburb, state, postcode. At the moment most the data is in address so the person awarded the job would have to go into each field and move appropriate data into appropriate areas. Now some addresses are already done but there is roughly around 4500 to 5000 that need processing. I only want bidders who can work fast and realistic pricing.
