Installing new wires in room with hardwood floors

There are a lot of plug receptacle options at Parts Express . com  I'd check with them, what you are trying to do is pretty straight forward.

I quickly searched and found this on Amazon:

I’m sure there are others available. 

Here’s the thing, you want a box made for mounting in a floor, with protection, as to install a standard box, receptacle, and plate, made for a wall, would allow dirt, dust, and possibly fluids to easily enter. A box, receptacle, and cover made specific for floor mounting provides some protection. The rest, as stated, is pretty simple for your case (simply feeding from the basement).

I run my cables under the floor (via basement), and then route them into the walls near my equipment a foot or so above the floor.
It requires a little fishtaping, but the floors don't need to be drilled into.
