That looks like to be a good idea, would'n that be something like a "Polished tech Fiverr"?
I just don't like the idea of "replace freelancers if needed", as you might know catching up with a ongoing tech project is not always easy, having the ability to replace the freelancer (if he is taking to long or something) might not be a good idea.
I would say that a normal/ignorant project manager using your site (those who understand tech as i understand oil platforms) will be always switching freelancers and he will lose interest in your service really quick.
Try to focus on giving both ends good reasons to be on your platform, not just for the guy that is hiring!

That's my 5 cents!
