First of all its obvious what you meant, 2 metre edge off gripper. You should always check all items you are going to work on. Clean a 3 peice with a rip down the back and you start cleaning and didn't see it, they'll have you for a new suite. 1-3K enough to put you out of business because your insurance won't pay it. When you make an insurance claim for a damaged item the first thing they want to see is your pre-clean survey with the customers signature.
You could probably put it back yourself but you'll need to buy a knee kicker.
Always good to have a professional carpet fitter to hand. He'll pull you out of the crap 9 times out of 10.
I don't know what you charge but far too many carpet cleaners have a job, not a business. Charge a proper business rate and you will have money enough not to worry about having to pay a carpet fitter.
