It is a solid minimum of 1 hour work for an astrologer to evaluate a horoscope using a computer and such predictions you can never get free. If the natal chart is presented to an astrologer prepared earlier, they can make a cursory examination and make observations which many a times will be far from truth. It is like going to a doctor and without doing the appropriate tests, he can write prescriptions which may or may not cure the disease. What we do here is make a thorough examination of a horoscope and then give our evaluations with useful numbers so that you can understand where you stand. Do read my articles on http://navagrahastro.blogspot.in/ and you will understand how we go about it.
Simple thing like what is your Rasi, or the Star or what dasa you are running and such other one word answers perhaps can be given free of charge.
Usually most of the questions after a paid consultation will be answered free for one or two days or even a week depending upon the astrologer’s mood.
