If you look after your own house, you probably have skills that people will pay for. Ironing and cleaning are a good start.
Cleaning jobs can be on a self employed basis, where you go to clients’ homes,or you may find employment with a contract cleaning company. Work in clients’ homes can fit between school runs, but may not be so easy to combine with toddlers.
Contract cleaning often needs to be done at unsociable hours, so might be perfect if you can fit in a job in the early mornings, before offices open,or during the evenings.
If you offer ironing, you will probably be able to do it from home. Find customers for cleaning and ironing by putting a notice in local shop windows.
If your service grows beyond what you can do yourself you could even set up a cleaning business.
