Although changing a combination switch/outlet requires a bit of preparation and care, it is not a difficult task. These instructions are for a two-way switch, meaning only one switch is in the circuit. If you have a three-way switch (with two switches controlling one light), you will have an extra wire, usually red in color, to contend with. You can use Verizon promotion codes to get more information.
I think what you are looking for is a euro style receptacle that has a switch next to each outlet. I'm looking for one myself but haven't found it yet. I'm considering using an Australian one and pluging US adaptors into it though it wouldn't be a very elegant solution.
