Job Board Website Idea

So I have a website planned out, and in most basic terms it will be a subscription to view a pool of job listings that cater to a specific industry so it cuts out the time of searching through every company's websites. I am looking for a no-code website building solution that would be best for integrating with an AI solution to scan websites for new job listings, categorize them into a pool, and list them on my website for subscribers to view.

However, cost is a big thing for me at the start and I am looking to get it up and running at the lowest cost and hopefully not pay a big monthly subscription for it. Does anyone have any recommendations or ideas that could help?
