Backup guestbook options?

My wedding is next week, October 11. We planned and paid for a photo booth to come to our reception. We were going to put the guest book right outside the booth for people to put a photo strip in and write a message. Guests would also get a strip for themselves and a digital copy.

It’s been two weeks of radio silence from the company. Texts are read but not responded to and calls go right to voicemail. They’re a start-up so it wasn’t too expensive, and I’ll deal with that after the wedding if they don’t show.

But, I’m looking for an alternative if they don’t show. Something relatively cheap (and returnable) to have on the side if they don’t show. Our guest count is 250 so a poloroid camera not an option with how expensive the film is.

Just a regular guest book with no pictures or is there something else we could do?

TIA
