Cleaner for three venues on Bermondsey Street

Hello, we need a cleaner to come and clean three art galleries in and around Bermondsey Street on a regular basis.
We need 5 hours over the weekend (not during the day on Saturday), or on a Monday, and also 2 hours on either Wednesday evenings (8pm - 10pm) or Thursday morning (before 10.30 am). We can try to be flexible based on your availability.

Someone local would be preferred due to the unsociable hours.
The work is basic - emptying rubbish bins, dusting, cleaning the floors cleaning the small kitchen areas and bathrooms. The Wednesday evening work would be cleaning glasses and the kitchen and floors during events, or tidying up afterwards on the Thursday morning.
(I know of more businesses which need cleaning nearby so the hours could be added to soon if desired).

We are looking for someone to start immediately.

We need someone very reliable that we can depend upon.
The job involves cleaning around artworks so much care needs to be taken when cleaning.

We run three different art galleries in SE1 - each is slightly different so it's about coming to each space when it's not being used to clean regularly. Also we run events once a week - usually on a Wednesday evening, we need help clearing up either as we go during the event or afterwards on the Thursday morning before the venue opens again to the public.
