If you want to spend a lot of time, $ and effort without a lot of bang for your dollar, go with Salesforce. otherwise there are a lot of good products out there (some mentioned above). i really like Insightly - because it is easy to use, lots of great simple reports and followup features, and you can link different people to to each other so you know who knows who...

This is a great list, and one which really applies to many 'consultant' or 'professional' type services as you mentioned.

As Russell mentioned you just call the cops and let them handle it.
