Website Developer for English Online Site

I'd like to hire someone who can create a website that will meet the needs of my site. I'd like to have a website that customers can create their own accounts, manage their bookings, reschedule, cancel, message the teacher that they have chosen using the website. I'd also like that my staff or Teachers can create their own accounts as Teachers and they can manage their own schedules, plot their schedules, customize hours that they can teach. message their students using the website. I also want a website that I can receive payment online using credit cards, PayPal. A website that has multiple languages that automatically generate depending on their country. I also want a website that customers can give their feedback and rate each teacher. I want to have an option for discounts whenever I want to give discounts. A good example of a website that I want is Amazing talker.com or Preply.com.
