Ease of customization

Hi,

I would like to buy this template, and wish to know the following:-
1. how easy or difficult is it to customize it? I am a joomla website designer for over 4 years.
2. What happens when you click on buy ticket?
3. Is there an ecommerce component for buying the music? Which component is used? I would like the users to be able to buy the music either as albums or as singles.

1. As any other regular template
2. This is just visual example , there is nothing in back to handle that. you have to install virtuemart or something like that
3. (answer in 2. )
