Hello, i've been using python for web scraping for 6 years, which can be used in your website easily, the process would using the script which will append the acquired product in your db where your wordpress website will grab them from there , so the databse would play as an intermediate between the website and the script. (or it will grab from a generated csv, both ways work :D)
Also, scraping 5-10 products can be done manually so you should've asked for more, my main field of expertise is web scraping/task automation (selenium,requests,bs4,urllib3...etc), and i'm mostly in this project because it's interesting and i can complete it in 12-36h, so if cheap quick and effective is what you're looking for, then i'm your guy ^^
feel free to message me anytime, can't wait to work with you :D
