Milage Lookup In Excel

I need an excel spreadsheet which will look up driving distance in miles using two postcodes.

For example:
INPUT
A1= ME15 9PF
B1= BS29 6ET

OUTPUT
C1= 179

I used to have a sheet that did this using a formula that looks up the mileage using google maps but they stopped it at their end.

I am told that it can be done using VBA and bing maps but its over my head. Having a look up for driving times too would be nice, but the mileage is essential.

If you can get this done in the next few hours then put in a realistic bid and its yours. I do need this done pretty quickly though.
