Auction/classified site - repost

I would like someone come with an offering on building a auction/classified website. There is plenty of ree auction/classified sites. So I know you not are doing work from scratch. Thereby the low price. The important is that other forum and website owners can connect easily to the website and their members can post and ad bids/buy. This regards to different types of forums and more. IN YOUR OFFERING YOU NEED TO EXPLAIN HOW THIS CAN BE ACHIEVED. JUST A AFFILIATE LINK ALONE IS TO WEAK. FORUMS NEED TO BE ABLE TO SEAMLESSLY BE ABLE TO AD MEMBERS ETC TO THE AUCTION/CLASSIFIED SITE. Description: - affiliate system - the site can be connected to other forums easily by forum owner or other, the forums member that use the auction/classified site will automatically be registered with the username, password and with forum affiliate tracking number. auction/classified website offers forum and website owners a commission on each payed ad set by admin. This must be easy to connect seamlessly for forum/website owners regardless of type of forum and programming language. - Auction/classified site: Good looking design and interface. All normal features -easy to manage - easy to set up - can run by itself. Needs to have usual administration possibilities, moderator set up and more. Paypal payment system Pay pal subscribstion for users that posts a lot. And more....
