Hi Sandy,
can I just add, 'depending' where they live, they may not come out for just one hour. Usually it's a couple of hours, pick a day that's the most beneficial to 'you' that fits in with your day to day routine, you may decide that's the end of the week or different. Decide what your priorities are, the jobs you absolutely need doing in a time slot. Ask them if there's any job they 'wouldn't' consider doing, that may not be evident at first. Work out how long a particular job may take and use your cleaner time to the best advantage. Lastly, definitely check them out, get a referral x
