Design of Classified Advert Style Website

I am looking for someone to design a website for the sale of thoroughbred horses. I would like the functions that clients/public can login and upload their adverts of bloostock for sale including pictures and details of the animal onto the site and that they will pay for this. Similar sites would include the likes of [[login to view URL]][1] and [[login to view URL]][2] and [[login to view URL]][3] . The site would initially be open to residents of England and Ireland however could expand in the future to Europe and further afield. I have previously got a tempate from built2go, the link to this is [[login to view URL]][4] and these files can be forwarded if required. I have a site [[login to view URL]][5] domain registered with [[login to view URL]][6] and would require the site to be uploaded to this location when it is completed. Please let me know what other information would be required and a price, many thanks.
