@cougars- If you are writing detailed proposals (anywhere from 10 to 25 pages), bid writing jobs can be lucrative. A bachelor's in business communication or journalism and a few years of experience writing and editing are all that is needed to make considerable money. If you are in a technology field, you can expect to earn somewhere in the range of 50,000 to 80,000 per year.
The money is good, but the job is very high stress. You must meet strict deadlines, and you must flawlessly explain the product or service that you are promoting. Any government work also needs to be in compliance with RFP standards. Not following these standards can result in an automatic disqualification of a bid.
