We are a team of 6 Web developers who started this company webkraits. We are new on freelancer and registered profile today so no reputation info here.
Now about the job. I will make the chat widget for you from scratch. It will be made by the use of AJAX (Asynchronous javascript and XML). theme of the widget, Placement of the widget, Functionality of the widget all will be according to you (Plus point of building something from scratch.).
I will need full website source for completing this job. As the chat widget needs to know who is chatting with who(its not simply a public chat).
Thankyou
