Hi
At the end of the day, no employed cleaner will do as good as job as you, this is a business for you whereas for them, it's just a job, usually to fill in some hours, they don't see it as a permanent position, unless as already said you are a huge company and can offer benifits.
Also to keep staff you need to pay a 'decent wage'. Minimum wage, is, lets face it, poxy, you need to be aiming for £6-7 p/h and finding a cleaner who can drive is like trying to find a gold nugget on the high st.
You basically need a huge pool of cleaners from a list of people who have applied for the job advertised and you employ until you find a good one, maybe invest in them by paying for them to drive (which is offset against costs) and saying in the contract that if they leave before said date then they have to pay for the lessons or if staying for one year they don't, pay for a bics course etc.
