Adding products to the online store on Opencart

You need someone with experience at Opencart. With experience in importing goods.

Periodically, you need to add new products from the supplier through the unloading of xml.
I provide ready-made uploads with full information on the goods.
Next, your task is to upload products to our site observing the criteria.

I did this through the paid Import/Export Pro module from DevmanExtensions, then uploaded and then edited the necessary data in Excel and loaded the finished one again. I can tell you on the operation of this module if anything.
You can choose your method. It is important that there is already some knowledge of how to do this.

The general task is to fill in all the data that are in the unloading for each product, while observing a single average style of design.
Well, in general, so that the product card was ready for work and had a good look.
Tags that are important and will need to be filled in the final form:
- Name,
- Description (without references/left images, etc.),
- Prices,
- Model (internal designation/supplier name)
- SKU (find last and continue/step 3 numbers: e.g. 237553, 237556, 237559, etc.)
- In one of the FIELDS UPC/EAN/JAN/ISBN/MPN is inserted Vendor Code from the upload to bind to automatic update
- Characteristics (in attributes)
- Photos (upload from uploading the quantity that is / all photos without watermark, if it is then cleaned via Photoshop or find a replacement for these photos)
- Url (must be filled in by hand in excel through the creation of CNC well, or through the module)
- Categories - Links (scatter by existing categories on the site collecting all links from the first to the last)

Payment 5 rubles / position

The work is long-term and periodic, for several thousand goods.
