I'm a Freelance tech support specialising in personal service to small to medium size organisations and have an extensive list of happy clients, most of whom are in London.
I've been doing it for over 30 years working mainly in the creative and artistic industries.
I've always specialised in Apple technology but am well versed in PCs and cross platform offices too.
I don't actually 'sell' any equipment so any advice is utterly impartial, balanced, and intended to be the very best for your organization's needs.
