Like the commentator said above, get another offer. Obviously you can't get it from this outsourcing site so you'll have to find it somewhere else.
What's the outsourcing site? They're probably billing you out at $100+/hr. They don't want to pay you more because they don't need to. You've stayed for 2 years at that rate. They don't need to "try and squeeze" anything from the client. They are the ones that don't want to pay more.
