Modify Google Base Feed (SQL Query) in Volusion

We are currently exporting our Google Base product data manually in Volusion. I would like to create a Saved Export with all the required columns and fields as required by Google. Volusion's Google Product Query only pulls the basic product info, i want to add all our already formatted columns to this query plus strip out all the uneccesary info from this query for $60 I would prefer a provider with some Volusion backend experience.
