Custom CSS Store Magento (desktop and mobile) responsive and modulo settings

Dear, I hired a magento developer to start changing the requirements below, most of the adjustments have already been made to the store, I just need to finish what the developer could not do. Basically they are adjustments in some details of the page. Note: I have all the pages in PNG to follow by example and to exemplify the details that I need. Note 2: Create the respinsiva for store, specific for mobile and tablet, I have PNG images as the model for each detail and how the pages should be on the cell phone. Note 3: I need the developer to be expert in magento and CSS in an advanced way, to speed up the adjustments. Note 4: Maximum deadline for all adjustments including the respoinsiva part for mobile 5 days (ending on 07/07/2017) Note 5: Depending on the quality of the work performed and the speed, we proceed with a second project and then a 3rd project. Note 6: This store will be a magento platform for use in multiple domains. - Change the Header frontend as attached image - Change the header of the Shopping Cart header as attached image - Change the frontend of the Product Catalog Page as attached, are two styles for the catalog, with left column and top column. - Change the frontend of all Product Pages as attached image - Change the front of the shopping cart page as attached image - Change the frontend of the Registration Page as attached image - Change the frontend of the Login Page as attached image - Change the payment page frontend as attached image - Change the frontend of the Success Page as attached image - Change the payment error page frontend as attached image - Change the Client Panel frontend as attached image - Change the modal layout of the buy button as attached image Note: Please remove any CSS Class that is no longer used in the store after the changes.
