Build an Online Store on Wordpress Woocommerce using Flatsome Theme

I current have a website I would like to move to a Wordpress Woocommerce using Flatsome theme (already purchased). This will be starting fresh on a already available new install on GoDaddy hosting. I will do all the graphics required, banner ads, logos. Flatsome is already a responsive design, but you need to make sure the website works on all device/browser platforms correctly. I run a website that uses drop ship vendors. All my products and image links come from a master file that the vendors supply (all files are different format, but I have transformed them in one format). These files contain the full product information files that need to initially upload into the website. Once this is done then the vendors have a daily inventory/cost update file (referenced by sku number) that need to be uploaded into the website on a schedule that I can change (from 1 to 24 hrs). The inventory upload file from each vendor is is a slightly different format so a template file needs to be used to map the headings. You will need to setup the first few vendors (2-3 vendors) and I will need (easily) to be able to add more later. I realize a lot of these features I am asking for are standard out of the box Woocommerce/Flatsome them items, but will list them anyway. I can buy any addon that you feel is needed to accomplish this task successfully, like file uploaders, emailers, cart systems, shipping calculators etc. See attached file for most of the items I am looking for. I can also show you the current website back end for some ideas. I am under no time constraint as I already have a website, but would like this completed and live by March 2016. I will need some email website references of projects that you have personally completed that are similar to the my requirements. If you have done drop ship websites before you will have the advantage.
