Build my website -- 2

I have a website but I have not built it properly so I need an expert to build it for me.
mostly I need about my website is

1. scheduling for my classes of salsa, bachata, and chacha. Group & Private lesson.
2. e-commerce like selling my videos of lesson.
I hope I could easily upload my lesson videos there and get paid through Visa or Paypal.
3. Working well on mobile.
4. I do not have enough pictures and videos for my website so I want to upload easily once I have them.
5. Managing people's contacts once they sign in.

Basically I am a Dance instructor & Choreographer I need to upload my pictures and videos easily.

My website is www.vancouveron2.ca
And I use WIX
