1) Place retina and non-retina logo
2) Remove the big white space below the rotating slider in the homepage without breaking other pages.
3) Static page links (gallery, about, contact) don't appear in mobile view. They should appear.
4) The contact link on the top navigation should refer to [url removed, login to view] not /contact. And /contacts should include physical address in the left column.
I will be asking questions beforehand to ensure you understand what needs to be done.
