Most important thing is to go and look and then put a price on, never ever quote for general cleaning over the phone. On written quotations always have lineage of "price given is based on condition of property as seen on (date). Find out when the clean needs to be done, if more than a week away add 15% to your price, cos you can be damn sure no cleaning will be done between you quoting and cleaning!
For end of tenancies, ask if the agent/landlord has a spec of what should and shouldn't be done. If no spec make one with the clients as you go around and list individually on the quote.
If people moving out....cash only.
Solutions will depend on depth of clean, so really you can only tell what you will need when you see each job.......some bathrooms would just need a general solution and some will need descaling too!
Vacuum cleaner
Mop
Bucket
Cloths
Those 4 really should be enough on equipment.
You will never be right on pricing......some round here charge £8 per hour, some charge £15 per hour.
Here in the sunny south (not) we get around £180 - £230 on a four bedroomed house dependant on what needs to be done, that would include windows in and out aswell. Man Hours required would be 10 to 13 ish. Carpets would be extra.
We tend not to do these sort of cleans on their own (unless they are mega money

)
We package it as a multi clean with carpet cleaning, window cleaning and general cleaning and then we can discount if necessary, if we want the job.
Hope that helps
