Create a full jewelry website

1- design and build a simple website for a gold/jewelry company. Website would need to be designed first and then build needed function : - Menu with pics - possibility to select in the menu by : Color (of metal : yellow, pink, white) and it will change the pics showed to the customers - metal : silver or gold -shape of stones : round, oval, princess, cushion, ... -style of ring - ring size - i can add video for each model and each color of model. - customers can choose the size of the stone / and choose another stone - i want to désactivated right click to avoid the possibility of download my model - share button for : FB, Instagram, twitter - a function where i can change price easily for all models. or to change it according to weight and stones, something like ratio. - the website in two languages at least (and the possibility to translate every term by myself) - last view products : must be shown when people visit the website - Logo must be beautiful and simple - i will provide some pics for the design - website must be responsive on IOS, android, windows. - Admin page must be easy to use - the possibility for the customer to take an appointement easily without to changing page. the website must be simple, elegant. the same website will sell coins and bars (ingot), and also stones, so it must be veay clear. design of stone, ring, coin, must be in litthe graphic in the menu. SEO has to be in the mind of the developper. This requires both front end development and back end development for administrative purposes. I am looking for someone that can create a flexible system that would be easy to go back and modify/make necessary changes in the future. Something very important :i had already do a project similar, and the website already doesn't work ! So i don't pay anything until the work is finish, and i'm totally satisfied !!! I only provide the server and jewelry models. If the freelance do good work, i will hire him again fo other work.
