I would highly recommend Sylvie Garvey who runs Computer Fitness http://www.computerfitness.net
I recently had some problems with software on my computer. Sylvie visited my home and was able to identify and sort out the problem almost immediately.
Sylvie offers a range of services including IT problem solving, web safety and parental controls. She also runs IT workshops and back to work IT training. Sylvie is clearly very competent and knows her subject inside out. She is a mum and is very nice and approachable and talks in a language that a non-techie like me can understand!
