Boat Trading Website/CMS/Directory/

Hello, I need a website that will list boats for sale and will also be a yachting directory for businesses if the sector. There are some websites that I can refer to so you can fully understand my needs. I already have a website named boatguide.gr. It needs to be corrected in the ways that I need and to have the functions that will make it work like a dream. The website is in PHP/MySQL and I need to redesign the pages and to correct the database to make it fully functional. The website must have an admin panel for all the content of the website and also admin panels for the members. -Banners function -Automatic Member Sign up with e-payment -Members admin panel for the content of each member -Search Script that will index EVERYTHING -Everything else that will make my life easier and the members satisfied Also a lot of data entry with information drawn from a specific website is needed to get the content of my website to the maximum. More details on the project will be given to bidders. Thank you all,
