I've picked up a few machines that will fold multiple sheets of paper and insert them into an envelope at the push of a button. The one pictured is about medium size. They get as small as a microwave and as large as a car depending on your volume. My factory certified technicians have refurbished them and we're ready to resell them. If you've got a job where you need to fold and insert paper, email me the details and I'll let you know what new and used equipment I have that will do your particular job. Prices range from $1,000 to $17,000. The one in the picture is just one of many. How much it costs depends on your volume and how many pieces of paper you want to stuff in the envelope. No job is too weird or specific, these things can do it all.
