One thing I would like to point out to people as a decent resource, for writing jobs, is Odesk. I see people slamming it because there are a lot of very low paying jobs on it. A lot of people are not willing to pay more than a few cents per word. The thing is that these low jobs will be offered because people are willing to take them.
I admit that when I started out, I was one of the people taking them. I had nothing and needed to build myself a portfolio. As I built up my portfolio and work history I started asking for more money and I got it.
The key is to ignore the low paying jobs, or apply any how, but at your own rates. The worst they can do is turn you down. Most of my newest ghostwriting work is coming from there and believe me I am getting much more than $1 per hundred words.
A few things to keep in mind when apply for a writing job (or any for that matter);
1. Take it serious, apply like it’s a REAL job.
2. Don’t do a generic application. Actually take the time to address the potential client and let them know why you would be the best applicant.
3. Pay attention to your writing. If you are applying for a writing job, you application should reflect your skill. Make sure your spelling, punctuation and grammar are all correct.
4. Give them access to a portfolio. If you don’t have one, then create one. I have a blog set up so I can refer potential clients to my portfolio and they can see the variety of stuff I have written.
5. If you mostly do ghostwriting then write some extra articles on your next project and keep them for your portfolio. Use them as examples of what you can write.
