Assistance Required With Current Website created through WIX & Help With IT/Website Tasks.

I am looking for someone to assist me with the finishing touches of my website via WIX (premium plan). This person MUST have a thorough understanding of WIX & how it works & must know everything IT/Website related. You will need to be able to complete the tasks listed below. - Change website around to mirror a similar layout of an example website which I will provide. - Create shopping cart / Add to cart options. - Ensure the website is Multi Country Friendly. - Help me with integrating payment methods to my website. - Integrate shipping costs which needs to be calculated upon checkout based on the country in which the product would be shipped to. This is for a new business which has not long started, I would need the freelancer to provide guidance with the website & be able to identify any areas I may have not covered in order for my website to be complete. I am expecting there to be other website related issues along the way in which I may need further assistance. This job requires a Skype call in order for me to understand how the freelancer plans to work on things & also for me to explain in more detail. The worker also needs to be available to calls if & when required. Thank you.
