I have been helping people write resumes & cover letters for over 4 years now and am thinking about doing it on the side for extra cash. Does anyone have any ideas on how I can go about this and where to advertise?

I’m new at this job thign & i usally don’t have to write resumes but what are they, how do i write them & what should i put in them?

-thank you

Actually what exactly is a cover letter? And what should it contain? And is a cover letter really effective? How can we make full use of a cover letter especially for an IT job? Thanks

PS- What is the better way- to first call the company telephonically or first send the resume & cover letter and then talk telephonically.
