Woocommerce

I have a website that is hosted on the professional version of WordPress and it has got the woocommerce plug-in activated. I am looking to add my products and have a simple but attractive E-commerce website where I can sell my products. Initially, I was using izettle e-commerce solution that integrated with WordPress however I am looking to integrate several platforms such as eBay and Amazon to name but a few with the addition of others going forward. I have tried to adjust woocommerce via my website and it's not as easy as I had hoped and could do with somebody helping me get the set-up correct so that I could maintain it from there. hope you can help.
