Here is a sample ad for a computer consultant.

Expert IT Support for Law Firms

Large firms have in-house IT specialists.

But if yours is a small firm, you probably spend time mucking about with computers when you could be doing law. And there are probably other times when not mucking about with computers puts your practice at risk. E.g., when you're in the final week of trial preparation, do your data files nonetheless get backed up every night?

I understand how law offices work. Chances are that I can help your law office work better. I'm good at solving technology problems. I don't have all the answers, but I'm very, very good at finding them. And my hourly rate is less than yours.

That is the start but the formatting was so bad I had to take it down. Will post again later for you computer consultants.
