How much is the level of the national calligrapher's works?

There are many national calligraphers in China. Some time ago, due to the need of work, I asked Mr. Fu Jianzeng to write an inscription at a price of about 5,000 square meters. This gentleman's calligraphy style is very distinctive, and he is good at cursive writing, especially left-handed calligraphy. He is currently the vice chairman of China Artists Association. Other details can be found in the information.
