Build similar script to another website into wordpress

Before I describe anything the websites that I would like to have similar functions are [login to view URL] [login to view URL] I already have the website up and running. We are still under construction. We are running our website with wordpress and the design and template is already done. All we need is someone to code a script that has the following functions. The functions are simliar to the ones you see on Livemixtapes and datpiff. We would like for people to be able to browse through the mixtapes uploaded in grid format the users will see the cd cover, some extra information such as how many times it was downloaded and the rating system. For example: [login to view URL] or [login to view URL] We would also like a custom branded audio player where the visitors can listen to the mixtapes or mp3s from our mixtapes such as: (where it says PLAY MIXTAPE) [login to view URL] they have a custom player branded and styled to thier own taste. For the backend or admin/panel in wordpress is where I can login and edit anything I need to edit code/script wise or even upload or add new pages or mixtapes. I would also need for people to be able to sign up for free, with a custom built form (i would specify that upon hire). The form will be separated in 2 ways. One signup for regular listeners and one for dj's. Both forms will have different questions. Once the user is registered that person can update or change ifnormation on their profile. like a little community. and then the regular listener or the dj can upload files such as .zip files or .rar files.. they would be uploading mixtapes. Please look around the sample websites to be clonned very well because we want it almost 90% alike. If you must create an account with them for free to feel the experience then please do. We will pay good for this project. We would like to get started as soon as possible.. We do not mean to rush anyone but this project needs to be done pretty quick aswell. If you need someone to design for you we have a designer on board who can do that for you.. If you decide to do the designing yourself, please provide PSD from photoshop to customize or edit in the future. ALL scripts, and codes should be editable so we may change or customize in future. If business goes good we will also plan on doing an extra project in the future with an extra section of the website ONLY for videos.. something similar to [login to view URL] but with our own custom designed branded video players.
