how do i remove urls from google without a big budget?

Is it your site? If so, the Removals tool in Search Console is free, but it only hides the URL for about six months. To make it permanent the page also has to return a 404 or 410, or carry a noindex tag. Do both: Removals for speed, 404/noindex so it stays gone. If it's someone else's page that's already been deleted, Google has a separate refresh outdated content tool for that.
