How To Do a Batch Conversion of Pages 4.3 docs to Word?

With this new upgrade I can no longer use Pages for my business. While I'm going to hang on as long as possible to 4.3, I'm worried about what happens in a year or two. I'd like to convert all of my 1,700 Pages docs to MS Word docs.. Is there a somewhat simple way to do that? Find all .pages docs, open them, export them as Word file to the same location as original. That sort of thing?

Best regards,

Polly
