Need advice to start an online shop


I would like to have an online shop on my site. I currently installed woocommerce on my site but I haven’t start working on it yet. I heard you have a marketing press plugin that I could also use. I also thinking about buying Shopify.

I don’t know which option I should choose. Would you please give me your advice which of these I should use: woocommerce, market press plugin or Shopify?

Thank you
