Design Quote, Guru, Elance, Crowdspring

[MLJGraphics]

I'm new to the web industry.
I have decided to be a web designer as my main focus

I notice these sites like Design Quote, Guru, Elance, Crowdspring

I want to know your opinion on these sites before I start investing.
I'm not a rich man that can spend money like air
and I'm not ghetto poor.
But money has been tight and I want to make sure I made the right choices.

Design Quotes you need to buy bids for clients information
Guru and Elance - Purchase membership fee... Elance well you have to pay more later...
Xemion- you have to pay for listings
Crowdspring is a whole different matter. I have to design something first and the client
have to choose which is best fit. the only catch is I'm competing against hundreds of
designers.

What's your view on these sites?
