How do I create a telemarketing/existing client database?

[Guest]

I work for a very archaic company which DOES NOT use CRM software and thus I
need to create a list of my clients in order to more effectively manage them.
I will need to include: client name, annual/monthely contract value,
contract start date, contract end date, contacts within the company and
contact telephone number/email addresses etc, any subcontracts and their
relevant start dates and end dates too. Any ideas?....

That sound like such a widely-used application that the first thing I'd do is
look for something off-the-shelf. Nothing's as easy as it seems at first and
the hours you spend developing your own will make a hundred dollars or so for a
commercially-developed tool seem cheap by comparison.
