Build me a Shopify Website

I want someone who is able to import my data from an “almost built” Website (ECwid) to Shopify and insert an event calendar widget. I need to be able to sell my products and my classes online. I have spent too much time and money and still don’t have a website! I’m frustrated and need help. No fancy talk and promises you can’t keep. Just let me know if you need more information. Thank you in advance.
