Modules on Clipshare script

Hi all, I need a coder to help me with my clipshare site, i need some modules developed there . I will write here some of what include the document and i will send fully doc on PMB . - advertising will be a bit touched (clipshare have advertising options, but i need something edited ) - search should be modified a bit, so only upgraded members to use the advanced search feature. - a dropdown menu with three option normal, smaller or no ads next to every type of member option (non-member, member, premium member). The idea is that the admin can set to every type of memebers with a single click to see normal, smaller, or no advertisements. - Admin mass upload feature - New integrated billing system - On the video page I want a button to download the video which is being watched. Only premium mebers can download video. If a non logged in user or a normal member tries to download it the script has to offer them to upgrade their account to a premium membership and after that they can download every video what they want. Basically are not hard updates. I am looking someone to start now.
