Looking for London based designer to offer adhoc client support

Hi 

I will soon to handing over a client website for which I will no longer be able to offer ad hoc support when it comes to customization, admin or technical support. She is London based and I would like to direct her to someone also from the area that could on occasion and needed help her with changes even menial as I think managing the site will be a challenge for her. 

Later work could involved setting up scheduling and Gmail suite. 

Let me know if there are any of you who is doing this kind of client support
