Hi there,
I would love to help you in building a website. I am not expert in building extension for google chrome, but I have done this kind of projects in past years. So, hopefully I am confident I can do it.
Please share all the details then I would have more clarity about the work. I"d require website admin and ftp access to work on it and Cpanel logins as well.
lets do it.
Regards,
~ Syed
