I need a very professionally designed website with an simple database

My website will allow users to type in model names of mobile phones and retrieve price, and then adds this to a cart which gets sent as an email to the administrator of the webpage. The webpage should be very easy on the eyes, both in the colours and the design. There should an easy way for admins to enter mobile models, their value and picture. Hopefully, simply an uploading of an excel document for example. The page will consist of the parts: **1. Home/Main page** Here one will be able to type in mobile models and checking their value, and putting them into a "cart". One will also see a list of chosen mobile models. **2. "How it works" page** Here there will be a basic and graphical explanation of how the process of selling mobiles to recycling works. **3. Search page** Here one will also be able to type in mobile models, and search for their value. **4. Contact page** Here one will be able to contact the administrator with a contact sheet. If you do not plan to do this professionally or relatively cheaply, do not bother answering. Best regards
