Ongoing web management with some initial development

We are a professional services member organisation and we need ongoing website management support at an hourly rate. Its difficult to predict how many hours per week/month will be required but I guess anything from as little as 1 or 2 hours a week. Initially we also want to do a review of the website - we have got what we want be there are elements of the CMS that may need to be improved and not all the CMS functionality seems to work properly.

We anticipate that we will want a relationship with an hourlie that can be something long term.

There is likely also to be some social media management.
