Build a Website -- 2

I am wanting someone to create an intergraded sound effects library using Wordpress/Woocommerce. This is a build from scratch, we need a creative developer to take the skeleton functionality and built it into woocommerce with modifications as to how the layout of the sound effect results will be presented. The basic tasks I will need the developer to achieve are: Front-end Search: Users will need to search via keywords. Sounds will be uploaded with descriptions and tags. These will be the two hooks used to determine the relevance of the results per search Tags: Tags will be a fundamental part of the search with users being able to click a tag to search for more or combine them to create bigger searches. Search results must be displayed in a list much the same as [login to view URL] We require the each result to have at a minimum: Preview play (with waveform) display), description, tags, length (sec), price, add to cart and social sharing functions Users will not be required to have an account to purchase but we want to push for that. Payments will take place via PayPal. Sound effects must be a custom post type as we will use the main blog as a blog. Homepage must be a static page, we will work out what to go there later. Back-end We need to have a system to upload sound effects. This system must automatically create an MP3 preview, assign the wav file (amazon s3), read and assign the length, format (bit rate/sample rate) to the search result. Add price etc. We want to be able to assign a user role of 'contributor' to any user which allows them access to the upload plugin. This must allow bulk uploads and single uploads. The system must be intuitive. It could read from a CSV or could be drag and drop. Contributors must have access to accounts to view realtime sales. We must be able to have a commission split and this must be set by us admins.
