Pedra.so is a popular virtual home staging tool used by 5000+ real estate agents 
You upload photos of an unfurnished or run-down property, and Pedra’s AI shows you what it would look like once furnished / renovated.
Here’s the idea: use Pedra on behalf of real estate agents.
They send you the raw photos, you send them back the staged versions, do some quality checks to make sure everything looks good 
Sure, the agents could just use Pedra themselves, but there are lots of older people in that line of work who can barely use email.
Pedra is €29/mo ($32) for 100 images, every 100 after that = €20.
You could probably charge each real estate company €100/month or more 
Find agents with crappy photos on their listings, send them a few Pedra-fied versions as a teaser.
If they’re impressed, pitch them your on-going paid service.
