There is money to be made in Internet based PR, handling the online PR requirements for a variety of small businesses.
You need to build up a list of contacts and publications, their editors and journalists, and their e-mail addresses.
Directories with the contact numbers of UK based publications are available, some in computer disk format.
You can then issue press releases by e-mail as well as utilising Web sites, charging either by the release or on a retainer basis.
