Voice over female speaker

I am looking for a female voice over expert to speak the words in my book recently published. The book is geared towards mums so a mature professional/ articulate south London voice would be preferred and someone who can add to parts of the humour of the book- edited to ACX standard. The is an e-book that is 10,000 words. No rights to the book will be given to voiceover narrator and ND will need to be signed.
