It was a nightmare working with this webmaster as our team kept working continuously on this project for 2 days & nights. This webmaster will not tell details of project prior to start and then he would expect you to code 20 plugins for wordpress without paying. This kind of work involves atleast 200 man hours but he wanted it to be done with in 1 day which is not practically possible. He will disregard you, insult you and blackmail you for chargeback & negative review.
