Just make your own , put your name at the top list customer details, type of carpet or soft furnishing, work required, area, type of soiling, type of sub floor, then list your terms of business, include a disclaimer that you will not be liable for damage that MAY occur during the cleaning process or use of cleaning agents, unless caused by lack of care by operative. I have a template that was given to me by one of the companies that trained me, if you do a training course you could ask them if they have a form they could let you have.
