Upload 200 designs to mangacorta

Hi, I am the owner of mangacorta. I need to upload tinny platform 200 designs that I have ready to upload.
The process is the following:
1- Upload designs and enter name, tags, category and subcategory.
2- after some processing the design is ready to position in the products. So you need to position the design on the products (like tshirts and sweatshirts).

It is a pretty simple and reiterative job.
It should take 1 day or 2 days tops.
