How can I revive my water-damaged iPhone 5S?

Two days ago, I accidentally dropped my phone in a dish full of water. I didn't realize I had dropped my phone in at first, so it was probably in the water for a good 2-3 seconds. Then I wiped it off and laid it down in rice, covered it with rice, closed the container, and left it in there for about ten hours. When I checked my phone the next morning, it wasn't turning on. A few hours later, I put it in the rice again, and its been in there for about 49 hours now. I have taken it out 3 times in the 49 hours to check on it, and it still won't turn on when I plug it in or hold down the power button. Is there a chance of reviving my phone at all, or does it sound like its beyond repair? What are some other efficient ways to draw the water out of my phone?

Yeah the rice trick doesn't usually work. Chances are that it is dead. Trying to get it fixed will most likely cost more than what the phone is worth.
