It looks like you want to enter into matrimony for the career success and returns from career of your bride and not for the marital happiness arising out of marriage. What is your primary objective of getting married?
Simply by matching of nakshatra and marrying someone is like looking at the paint of the car and buying it when there are many other important considerations to be looked at. I am afraid your priorities are all mixed up and that could be the reason why you remain unmarried even after 39 years of age.
Marriage is for a good partnership in life and having good off springs, and wishing for a doctor as your spouse is ok, but these are in the hands of God and we have to accept His wishes in life and one cannot find out such things using Astrology. Yes if you find a suitable bride, we can match the horosocope and establish the compatibility of the marriage.
