Changes to an article directory script

I need this script edited: [login to view URL] Please download and take a look at the source - I only want real bids I do not want any low bids saying 'message me for deatils' take a look at the script yourselves and quote me please. The changes I require are: Theme (design improvements) - These shouldn't be too hard Improved wysiwyg editor for authors so they can easily upload images Ability to upload a featured image for the articles A slider above each TOP level category that pulls in random articles from that category using their feature image Thumbs up/down below each article so people can vote Author information shown to the right above where adsense currently is (when viewing an article) The ability to 'Rank up' allowing people to earn writer statues You can see a dummy version of the script here, with one article on here: solelyarticles . com Thank you
