Website design/build for protein powder distribution company

Design and Build Webpage for a company that distributes protein powder. Logo and product already designed. Prerequisites: - Simple and modern with few menus on the top. One of them will have special requirements, what we call "code verification". - Code verification details. There will be a box where user will enter alphanumeric code to verify and once it's verified will redirect users to newsletter subscription page and their id will be saved in database. The verify button will compare the input string with the list of strings in the database. Database should be configurable, so we can add and remove the list of codes ourselves using csv or other formats. A configurable text is displayed depending on whether the string is a match or not. Webpage should record the IP address and date of intend of verification. - Newsletter subscription page linked to Code Verification - Page needs to have a mobile friendly version and should load quickly even with slow internet connection. - Not e-commerce required for now. - SEO optimization would be nice to have We are looking for relevance experience in similar web designs, not only template configuration
