Take photos and replace heads.

Hi all

I’m trying to see if midjourney or any other ai can help with marketing my sign company.

I’m a one man band so i need all the help I can get. I want to start marketing on social media and taking images of vans are boring and not very interesting. It’s the same for taking photos of workwear. I’ve asked if I can take images of clients with their workwear on walking to their van etc but customers don’t want to which I get.

Is there anyway (without using photoshop) to take my images and replace the heads with Ai so I get the photo I want without the customer being in it?

Or how can I make midjourney work for my business? I see lots of pretty images but none are suitable to help with promoting your business.
