Build a Website

I would like hire someone 1. to research an existing website we can use as a model of my requirements, (that way I can easily explain what might be different for my website, if anything) 2. to design and build agreed website, but first come up with their understanding of what needs to be done, which we can agree as general working model 3. to build in good (high level of security) 4. to build in multi-currency, display and charging 5. to make site responsive to mobile device, and be linked to social media: eg. facebook, twitter, instagram, etc. 6. to commission and maintain website for 3 months, so that we can also incorporate use experience and suggestions in the design. 7. to complete agreed milestones in time and budget 8. to give advise on refining, improving, or simplifying approach and implementation Details: Here are examples to help explain better the kind of CMS website I am looking for: Example One: 1. a. university courses website, where universities' admins enter courses in a database,manually or by upload, and maintain own information and view and manage courses requested bu users 1. b. each featured university to have profile information: a bit of history, their faculties, no of campuses, academic staff, admin, ranking, etc. 1. c. CMS can display courses to the website by type (BSc, PhD, in any or preferred subject, etc) for visitors, guests, or students -- a student being defined as a visitor or guest who decides to sign up with and enter their details. The student then gets a user profile where they can list favourite courses and send enquiries to universities (on our same website, to be viewed and managed by universities admins by assistance of the website) 1. d. Alert universities admins by email or sms when students request courses or have enquiries. 1. e. Alert students by email and or SMS, for courses availability, application deadline, etc 1. f. CMS to include charging, invoicing, receiving payment online to universities (and students) for subscription, course, usage, adverts, etc., Anyone with outstanding payments after several reminders (by emails and SMS) is automatically or manually expired/disabled and their contents no longer accessible. 1. g. Website owner admin(s) setup as might be found necessary, for content and user management such as to unclock disabled users or other functions. Also to set charges, eg per course, for large, medium, small users, among other things. 1. h. Adverts: To have generous space for google, or other adverts. To have a way of charging differently for different pages, even if adverts are randomly displayed. Example Two: The same idea and concept as above as might apply for a car website: Website facilitates car dealers to list profile information about themselves and their different show rooms, and types of cars Users view or sign up and can list vehicles. Users can negotiate and manage the cars they are looking to buy Sellers and users can get alerts Have advertising space etc I hope these two examples give a clearer idea of what I am looking for
