I write several business columns for newspapers, Mr V., and my wife syndicates a cooking column. I think you should go for it! Write what you feel or what you know. Use spellcheck, and if you can, get a few people to proof it for grammar and "flow" or read-ability before you submit it. And write for your reader, not at the top of your knowledge. If they are the general public and yours is a very scientific piece, soften it up a bit, ya know?

Anecdotes, stories from personal experience, and simple examples are always good, too.

And as a personal thing that I do...I always end my articles with additional resources for my readers. For example...."If you'd like more information on small business grants, please visit my website at mysite-here.com, or see www.sba.gov".

Hope this gives you some ideas. Feel free to PM me if you have any specific questions.

PS. A good proof-reading trick is to read your article backwards from the end to the beginning. You'll catch many misspellings and double words that way.

PSS. Ask them to send you a printed copy of the article/magazine/newsletter. It's called a tearsheet. Like tearing out the page. lol. Then you can reference this writing experience on your resume for jobs, or in other places when you're looking for writing work.
