don't think the local chemdry is too worried about my prices, he passed me a commercial job last month. he was too busy and they wanted it done the following weekend so reccomended me, i was booked for saturday but did it sunday. lady at the toyota garage told me" we usually use chemdry but forgot to book the clean in and had to get it done last minute, chemdry was booked up for 2 weeks solid so reccomended you, said you were very good". Saying that, i have passed a couple of jobs his way.
FYI
takes me around 2 hours to do an empty or "don't move any furniture" 4 bed house. did a "move in" clean on a 3 bedder yesterday and charged my 3 bed special offer price. 1 hour 30 minutes, came up beautiful. customer gave me a hug she was that pleased. 
I cleaned 4 bed detached house last summer just up the road in sproston that had been rented by a premier league fooballer, the master bedroom was around 120 m2, I could have rushed it and cut corners but took my time and earned very good money direct from him for two full days work.
I do alot of work for a very wealthy and well known self made multi millionare on the outskirts of knutsford, the house is worth around £8 million, again the rooms are very large I take my time and charge around £50 per hour plus the vat.
No one job or property is exactly the same - so Imo putting pricing on leaflets and websites is daft
