I know of a few people who are seeking more writing opportunities this year, and I'm sure many more are trying to increase their income as freelance writers.
WriteThisMoment is an online subscription based site which provides details of writing jobs and opportunities in the UK and USA, as well as some from other parts of the world. Although annual membership is £24 (for twelve months), you can try it over three months for £8 which seems ideal for testing its worth for your particular needs. I'm about to do exactly that!
Let me know if you've used them before, or how you get on if you decide to sign up.
