i need help learning the worth of art pieces that i have

Old Bethpage NY

Description

I was asked by a woman to help sell her artwork for her. She obtained about 30 pieces for a cheap price and is asking me to help sell them for her. The artist is Itzchak Tarkay and they are all numbered and have certificates of authenticity. I need to know what they are worth and where would be the best places to sell them that would maximize profit. Also open to connecting with art buyers who are interested in the pieces. I have photos of the pieces. I am a young kid so you can just shoot me a text. 516 - five two four - 9 six two nine. Thanks.
