Bookkeeper

I am looking for a new bookkeeper to manage the accounting of my business. We have been trading for nearly 2 years and we use Sage and also have a factoring facility. Unfortunately my current bookkeeper has become too expensive and we are looking to streamline business costs for 2012.
One full day a week will be sufficient for the task although as we expect to expand next year there may be opportunity to increase this. This work can be carried out from home and I am prepared to look at some flexibility on which day is set for this.
Many thanks, Matt
