I have about 5 good reviews (in 1 year) on Elance but still very hard for me to get new jobs.
There are lots of users with huge reputation and also offering very cheap prices. So it's pretty hard to get in for newbies.
I don't know how bad is the situation in your category, but in mine (translations and article writing in Spanish) I get approximately 1 or 2 out of 10 projects I reply to. I have been working there for some years, and I guess I was lucky when I started, because, yeah, it is difficult to get your first job if you don't have any feedback, but with 5 reviews you shouldn't have problems, imo. Plenty of translators and writers with good reputation and a lot of jobs in my category too, but I'm doing well nonetheless.
Try to browse the previous projects the client has awarded to get an idea of how much they are willing to pay, spend some time writing your proposal and try different styles to approach the clients, to see which one works best. But well, you never know. Lately I've been thinking about posting a project using a fake account to see what are my competitors doing, but I don't know if I'll do it. It could help you improve your chances in the future.
Last year I was even running a shitty python script to know the bids that the rest of the freelancers were making, as you can see the number of bids, the name of the freelancers and the max/min and avg bid for the project. You can even do it by hand refreshing the page to get a general idea; if your price is higher than that of a fellow freelancer with better feedback and/or more past jobs, it'd be difficult to get the job.
