Zencart Product Datafeed Installation

Hello – I require a new, updated product datafeed file to be installed into my Zencart ecommerce website.

I use a dropship supplier who provides a product datafeed file, which I update daily through my Zencart Admin. My site is currently using this datafeed, approx 11,000+ products:

My supplier has now introduced a new datafeed, containing 19,000+ products:

I require bids from freelancers who can, back-up the existing site first, and then import/install the new datafeed file, and who can guarantee to complete this process. I require to be able to update the new datafeed file daily, through my Zencart Admin, as per my existing website daily update.
