Hello Sir,
I think to have the right solution for you but we need to discuss about the details first.
I have made a similar browser software for my last internet kiosk project.
I can reuse the web browser part and add the advert banners. To make you more detailed proposal for the entire architecture I need the details of your requirements.
To send you some screenshots please contact me back because the Freelancer.com system doesn't allow me to send anything before being contacted by you.
Kind Regards,
Patrik
