parser for online stores

Good days

It is necessary to implement a one-time parser of product cards using Php-jQuery with subsequent uploading to the site via Ajax
Ideally, I would like to see the following under WordPress

Frontend:
1-input to search for a key query from online stores by the selected user
6-checkbox
1.2.3 checkbox is aliexpress/ebay/amazon
4. seller rating
5. available products
6. number of reviews
1-Table for displaying 9 search results with the LOWEST (filtered) cost of the products found for each online store, 3 results from each store
3. columns (columns) aliexpress/ebay/amazon
7. lines product name, price, product picture, seller rating, available products, number of reviews, product link
uploading the entire result found in (docs & xlsx & pdf) does not matter what format is at your discretion

Backend:
integration with socks4 format: 127.0.0.1:8888 if necessary (from ip blocking) when crawling pages
filter data at the lowest price
Deleting the search result if the document is generated on the server after parsing
