Question
I know our quality of service is far superior, and I know that all the people (or at least 90% of the people) pitching lower prices than us won't be able to deliver an end product that will be of much benefit to the client (even if they do manage to fulfil the technical requirements).
We want to actually talk to buyers to figure out how and if we can actually help them, but most insist on us just sending a quote so they can screen everyone based on pricing before proceeding to discussions.
Answer
You've received a great deal of success from working on Elance, but as your question implies, it's time to get into the real world. Clients are all around, and they need your expertise. Take the plunge, you won't regret it.
Good luck.
