A letter of termination for cleaner

[Notfootball]

I no longer require my cleaner as my eldest starts school this month and I shall have more time to clean the house. How do I draft a letter of termination? She requires 30 days' notice.

Dear Cleaner

As my DC will be starting school in October, I shall have sufficient time to do my own cleaning. Therefore, please note that the last day I shall need you to come here is y date.

Thank you for all your help over the past years - with young children it has been a godsend to have someone reliable helping with the cleaning [or some other wording here depending how you think she's done and you've got on with her]

Thanks both!
