Be careful with this freelancer! He is not what he pretend to be! He can impress you by writing what he will do, but in reality he will not be able to do anything for you. After he received his payment, he said that he couldn't work in weekend, and after that he get flu, and after he told me that he couldn't do any program for me! He didn't deliver any work and any program at all! I lost 8 days waiting for nothing! BE CAREFUL !!!!!
