419504 ioffer Clone

am looking for clone (but with added features, change in look just clone of current features on the site) of [login to view URL] Must have the features but new look and added features as below. Administrative back end should be template driven (same as for example backend of PHPProbid and (paypal/nochex/2checkout/google checkout/egold and more) compatible for all fees paid. Check out [login to view URL] for features and functionality to familarise yourself. In addition to the site similar to iOffer certain features will need to be changed and the below added: This website is for a clone of [login to view URL] but of course a different look, improved features of the site (which i have added in project details : Ability to sell Digital goods Add favorite sellers to list Community profile to include skype, msn or facebook Ability to add youtube videos or similar to adverts for sale Adverts to be placed can be Make Offer or Sell fixed price Sign in and register lightbox with quick sign up ability to offer coupons to customers and abilty for admin to issue free credit and adding sideboxes with small adverts) i need to be assured you can do ALL of these extras plus of course the same functionality of the website [login to view URL] website needs to include (similar to ioffer) of copyright protection agreement,the website needs to have ability to be updated at later stage with addons and more functionality, The website needs to be as per websites like phpprobid with a CMS back admin to make changes to prices, images, functionality very same as changes that could be made by phpprobid but of course on this ioffer type clone and with sql and php functionality, website needs to be seo compliant, website will be a clone but certain menu will be desired to be different style, front page slightly different in what is actually displayed and some boxes will require lightboxes, all colors of site will be different. I am on a budget, would like this completed soon. Looking for timescale and total project cost and details on requirements. Thank you.
