I hate cleaning kitchens, I can`t believe someone wants to set up a business just cleaning kitchens...........
Every kitchen I do I have doubled my charge from the previous one because I hate them so much, yet I keep getting the jobs, so I guess that has to be a good sign for you as it seems to me that no one likes doing kitchens.
I would recommend you buy a decent steam cleaner, and charge plenty because they always take twice as long as you expect, my last one worked out at about 90 quid per hour and the custy paid it quite happily and booked us up for 6 months time, Great....got to do it again............I hate kitchens and your mad,
But good luck anyway...
