Contest Chat Script for students to integrate in some html pages $50

Hello,
I need a chat to integrate in some html pages for italian students
at this pages: http://www.universando.com/Cosenza.htm
http://www.universando.com/Verona.htm
http://www.universando.com/Venezia.htm

I offer $50, but it must be integrated to the pages

I wait for proposal

thank you

 

Do you need the chat script made or an existing one added to the pages?

 

also an existing one but i want it perfectly integrated with those pages without logo or brand of some company
