Build a Website

I need a new website for my IT Consulting and Agile Training small business (In person and online training). I need you to design and build a website to have the below features. 1. New customers (individuals, companies) should be able to choose the training available and register/enroll for the training. 2. Make payments using credit card or bank accounts. 3. Provide email to the above users about the registration. 4. Provide the terms and conditions about cancellation policy before the registration. 5. Allow the existing user who has already registered to open his registration and view the details and provide the ability to cancel or request for postponement based on policy defined. 6. Provide filtering capability for the list of trainings available with options to choose name of the city, country and date (month/year). For example by choosing July 2017, the list if all available trainings in all cities should be displayed. 7. Allow the users with a blog to start sharing feedback and/or ask questions about the training. 8. The web page should be with good graphics, images and texts. 9. Should be searchable in any search engine with text description and should be able to display at the top of the list. 10. Need more ideas than the above to have a state of the art web site.
