Classified posting site

I want to create a classified posting site, but with eCom embedded to it. The best example would be : [login to view URL] Where users can come and post ads. Registration fee will be collected by sending an SMS to receive a confirmation code. You need to be registered to post an ad, but you can buy directly by contacting the seller, without registration. Individual users can post basic ads at fee of cost. Featured ads can be added with some cost. The amount will be collected by SMS method. On the other hand firms need to pay for posting any kind of ads. Then once they choose their package they will be directed to either SMS or Credit card payment [login to view URL] can select a package and each package will cost according to the: duration, size of font or even color of the frame. like: package 1: post 10 ads : cost 10$ Package 2:post 20 ads: cost 15 $ It will Include the price and renewal price of the package. They will be notified by email about number of visitors of their ad, expiration and renewal date. The items on the web will be classified by NEW or Used.
