Budget: 25000 EUR Deadline: 12 days
Good afternoon. For the timeline, I would aim for 10-12 working days and a budget starting from 32,000 UAH, if the 4 websites are accessible without heavy protection and there is no need to bypass complex CAPTCHAs. The final price depends on the websites themselves - there is a nuance, a parser without an API sometimes looks simple only until the first anti-bot appears =/
For implementation, I see this as a separate service on a VPS - a module for searching across 4 websites, a queue of requests every few minutes, a database of already found listings, a TG bot with buttons for starting, stopping, downloading, and uploading a keyword file. The file can be stored as a working version, but it's better to keep the history of found links in the database; otherwise, deduplication will be fragile.
I would like to clarify 2 points:
> which specific 4 websites need to be monitored
> is the result needed as just a link or link + photo + brief description of the listing

To start, I will need the addresses of the websites, a sample file with keywords, access to the VPS, data for 50 IPs, and criteria for what to consider as the same listing. After that, a working version can be quickly assembled, tested on real websites, and based on the results, the protection against duplicates and blocks can be refined.
