Your request for having someone write some articles for you is a little vague, as you well know. Even though I'm struggling to make sense of the internet, and Freelancer.Com, I have been writing for years, explaining the needs and services of clients persuasively and clearly understood, in a way that would not make the reader feel like an idiot.
My work has been advertising, marketing and publicity and public relations. The internet may be new and exciting but words - the conveyors of the message - and the stories they have to tell, have been with us through the ages.
Why don't you think of the messages you need to communicate being trapped in a minefield beyond your understanding - how are effectively you going to find your way through that chaos? I believe you need an experienced silver-tongued story-teller like myself to save the day, and get your message out there, told with conviction. Call me - I'm not going anywhere for Xmas.
