FOREIGN TECHNOLOGY TRANSFER

DEAR FRIENDS, I AM RUNNING AN ENGINEERING INDUSTRY (PROPRIETORSHIP) IN AIR POLLUTION CONTROL FIELD.  TO IMPROVE MY BUSINESS, I FOUND A CONSULTANT ENGINEER IN UNITED KINGDOM WHO COULD SELL HIS ENGINEERING SOFTWARE TO ME ON RECEIPT OF PAYMENT.  COULD U PLEASE TELL ME WHAT ARE ALL THE PROCEDURES TO GET THAT ENGINEERING SOFTWARE ( ONLY A CD) FROM HIM? WHERE I CAN GET THE DETAILS?  I COULD NOT DELAY DUE TO THE FEAR LOSING HIM IN THE MARKET.
