public Quote GetQuoteFromPreviousPurchase(string username, string password, int resultsId)
If the calling application wishes to download the results of the same set of services as have been purchased previously,
this method can be used to retrieve the set of services that were previously selected rather than setting them up manually.
Note that the quantities and associated pricing returned by this method will refer to those in the original job. In order
to get an accurate quote for the selected services for a new job, pass the details of the services from the quote returned
by this method to the UpdateQuote method, specifying the name of the new job
you want to purchase those services for.
