recondditioned

I have a 2010 Ibiza fr 1.4tsi. I love the car but have been having some misfiring. Seat have told me I need a new engine. Anyone know anywhere reliable around South Wales that I can get a good reconditioned engine? Appreciate any and all help

My cambelt failed at 75mph, and as yet taken the car to the garage for diagnosis, but having spoke with the garage the feasible options are reconditioned or second hand engine. I have used some internet search sites and have managed to obtain a couple of quotations for what I guess is...
