In writing, my experience is that once you have even a single feedback, it will start to pay well. My best experience has been with Elance -- and in fact my best clients are all from there. They own the provider/buyer relationship for one year, so now I have a number of excellent recurring clients who are all mine -- I even gave Elance a few extra months before moving them off :).
I have been a full-time freelancer for five years now, part-time for about two years before that. Personally, I think very highly of quality bidding sites, but check over the fee structure very carefully. If there is nothing to keep people from simply bidding on everything, run away fast.
I love Elance because you are charged for every proposal you write, which means that you are only competing with a few other people. A well thought-out proposal goes a long way, as does learning the "red flags" that people say that tells you NOT to bid -- i.e. "this is a simple task for someone who knows what they're doing" (this is, invariably, someone looking only for the lowest price).
Going out on your own can be a very tricky proposition. You have to learn to really think outside the box of people to market yourself to, especially if you're approaching established publishers. Whatever pops straight to mind, probably also pops straight to every other freelancer's mind too.It can be very rewarding if you find the right match, but is often very heartbreaking in the pursuit.
I've tried couple of them and the experience is not that good. I feel it may (bidding sites) be good for programming and other stuff, but in writing and related works it doesn't pay you much. The bidding war is cut-throat and it always ends up with winner being the one who quoted the minimum price.
The minimum cut-off price is not that remunerative. I would suggest to go on your own.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
