Greetings... Hello, we are from the Shuffle Submarine Studios, a new and developing company focused in Art and Designs. We've been through your requirements and did some initial analysis on the target website, Next Models. About the features you mentioned and prefer not to include (the shopping cart, forum, and guest book), we could provide them with exactly no additional costs when you need them. That's all for now. We are more than willing to build professional relationship with you, and are looking forward to hear more from you. Best regards, Henry K. - Shuffle Submarine Studios
