Supplier xml woocomerce

I run a woocomerce store and want to add products from my suppliers
First supplier:
https://brandshop.gr/products.xml
I have done category matching
I am attaching files

Second supplier via Web Services REST API but also with xml
https://nortonimages.blob.core.windows.net/xmlfeeds/Availability.xml

Third party supplier:
http://feed.alfanet.gr/all-products.xml
(There are also separate categories)

Tasks :
- [ ] mapping from me to xlls file vendor categories and mine categories
- [ ] Generate profit rate
- [ ] Automatically delete products that do not exist in xml
- [ ] No deletion of products that are currently in the store
- [ ] Matching fields upon consultation with me

Immediate delivery... (I will choose people with experience in relevant projects, not offers people with no experience)
