Well Lewis from Devon I can tell you that a Steam pro will do you just dandy, most guy's leave their machines on the front door step and run pipes in the house. Other have larger electric machines with 3 vac motors and run them from their vans.
First thing you will need to do is get yourself either with a local carpet cleaner who can give you good on the job advice or book yourself on a cleaning course.
There are plenty to choose from i.e Matt at Clean smart, Prochem, Alltech, I'm sure if there are any more the seasoned people on here will let you know.
