Customise a Shoppify Template

Hi everyone, I've choosen the shopify template I want to work with (ELLA) and I need it to be tailored to my needs. I had all the PSD files been redone to the final design and the following is required to be done: - Divide the home page onto 2 separate pages (Home which will be the landing page, and Shop) - Change the login to a Dropdown Login - Implement Mega Menu with multiple levels and also showing different images according to categories - Each Brand to have a individual profile page (I'm thinking on using the category page for this) with a different banner and informations on top according to brand - Customize the Newsletter Pop-up in order to give the client an automatic one-off discount by send a email code - Add additional referral marketing – Tweet for discount & Share with friends in Facebook gives credit (if they make purchases in-store) - Add Pop-ups with shopping/likes being shown (such as [login to view URL]) - Change the Product page to have large pictures (I quite like this one [login to view URL]) where the picture is the main focus and information is held below - Product page with option to send message requesting for more information/advice directly in page (small contact form) - Some products with option to request to customize them (small contact form with the request) - Search Module to have better refinement possibilities (such as [login to view URL]) - Update colours/transitions/icons according to design Feel free to aks any questions you may have.
