If you run a business consulting service then you realize there is almost an unlimited amount of business out there, but most of it is very hard to get in your industry. This is because it is hard to convince people to hire outside consultants and some companies just won't do it.
Meanwhile we also know that unless you are known in the industry think no one will seek you out for your consulting services.This is where good public relations and industry goodwill come in handy.
A little bit of publicity will not hurt either and it pays to be an expert in your field and your customers or potential clients need to be able to see your name in print in the trade journals and read about your research.You can also browse http://daemon.co.in/services/technologies/crm/ for detailed information on these services.
The rest of the public relations is much about word-of-mouth and the seminars you might do at local trade shows or perhaps the books you have written. But even those need to be promoted because if you are at a trade show and only 15 people show up for that session then you are not reaching the audience you need to reach in order to make the public relations work.
