Will this work with my website? I want to make a mobile website for our company site.
The website is nwdecorativepainting.com

The theme does not support mobile friendly, and we have a lot of gallery such as nwdecorativepainting.com/index.php/2013-10-23-07-26-06/decorative-painting.html

Will we be able to make a site with premium theme in here that would also have a gallery included for it?
How does it work, will it import all our current articles and all the menu into the mobile friendly site?
will my contact form and free estimate be mobile too? 
nwdecorativepainting.com/index.php/contact-us.html
or is it possible to make the whole site comparable with that? 

Please let me know before I buy. And what to buy if that will work. 
Thank you!
