How to light floor and background evenly?

Hi,

a client needs a fullsize portrait on white seamless. I need to light the background and the floor evenly white.
I have seen Zack Arias using white tileboards from home depot to solve the problem, but that stuff isnt available here in germany.

What else can I do? I guess if I aim 2 rectengular softboxes at the floor, I m gonna overlight the shoes and pants.

And you also want to avoid multiple shadows in different directions. I did a lot of experimenting with this at one time and could never exactly match background and floor lighting, but it's a really easy thing to fix in Photoshop in post-processing.
