Can a silver plated ring be resized (bigger)?

I have this ring that was about $30, but its too small (it needs to be like a size bigger). I fell in love with it so much that I really want to get it re-sized despite what it would cost me. I looked at local jewelers (in Charlotte, NC) , but none of them would do it. Is there any jewelry repair place I can ship it to? Is it even possible to re-size a silver plated ring? PLZ HELP!!!
