glossy base underneath camera

I am boggled on how to do this I am a seasoned photoshop user but not sure how to do this. I want to take a photo of a camera and place it in ph on a glossy floor to walls. I know how to place a reflection under it but how to make from scratch a glossy white floor. Examples, tutorials are welcome, please help.

The thing about a glossy "white" floor throws a little bit of a curve in the whole thing. You see when people make things in photoshop look glossy they use white to simulate the gloss.

I can throw a quick image together like:


but I have to use a light gray ( I used a darker gray for illustration purposes)for the base color and then simulate gloss using white. However selling the effect will depend on you reflections.

You see what I mean?
