Add features to interactive tour.

Hello! here is the website we are talking about [login to view URL] The following needs to be done: 1 first we need to implement voice over option. For example, when visitor goes from one room to another he/she has option to listen for the description for that particular room. 2 second, we need to have an option to have online catalog with interactive pop ups. For example, visitor is in piano store. When visitor does mouse over on the piano, he/she sees the price and the other images of this piano. Important to show a similar project that you successfully accomplished already! Need to quotes.
