It is important that you choose a technology supplier that is familiar with the needs of small law firms with low IT skills.
You wouldn't buy a blunt pencil, so don't buy the cheapest technology. In fact you should buy the best you can afford. It will pay off many times in boosted productivity.
Technology includes communication these days, so don't be fooled into thinking you can do it yourself more cheaply than by paying a professional. Of course, if you want to do it yourself, you will be charging yourself out at a junior technician rate rather than at the hourly rate you have set yourself in your business plan! Don't do it. It might drive you mad.
These IT Providers do a lot of work with small law firms:
Convergence Technology Specialists - Manchester
OCS computing - Peterborough
Charles Street - London
Accutech - London
Gower Business – Wales
JMC - Manchester

It is often also possible for you to get your IT infrastructure funded so that you have predictable and affordable monthly payment.
