It's like a photo album. Facebook is good but those images get lost in the timeline unless someone is searching pics.
Take all those images and videos and put them in IG. Steer clients to your IG page. You can text or send links to individual pics that show jobs which clients are considering.
Once they engage with your picture it's much like Facebook. Better because they can see all the things you do.
Hopefully they follow you and you can run IG specials of the week, month, whatever. You can also put marketing pieces without the Facebook 20% text restriction.
