Craigslist, or even call local photographers and ask once they say they can’t do it for that price if they know anyone. Sometimes they have assistants trying get into it and are willing to do it cheap. Not sure where your located but also go to your local photography store if there is a local one and ask around or check their push pin boards. Go on the Nextdoor app, check Groupon (the wedding photographer I worked for did this when she started and now does 50+ weddings a year at like 10k a wedding).
