Build an Online Store using Magento

Hi there, Thanks for taking the time to review this project posting. Attached is the rough draft of what the final website would look like. The shop should be built on Magento CMS unless you specially recommend another CMS. PLEASE REVIEW THE ATTACHMENT BEFORE SENDING OVER A QUOTE AND/OR PROPOSAL. For the Shop/Magento piece they're pages 7-9 from the PDF. There will be a final creative which will have slight changes (color, fonts, etc..) but this PDF represents the majority of the product (UI + Functionality). Here are the minimum requirements I'd need so far: 1) Setup Magento store • Import products into the store (products will be provided with images, description, etc..) 2) Create a theme/UI for the store from pages 7-9 • Include Header and Footer with Navigation • Include Product browse page with Sorting by Category and sub category functionality. • Include Product detail functionality (I still don't have detail for the Add to Cart functionality yet but assumed something will come) 3) Expose API for WordPress website to consume • Top 5 selling products for example • This one will be in Phase 2 but just wanted to make sure it's in the picture. Please review and give me your estimate for low, medium, and high of what this piece would cost me.
