Can someone tell me how I create video like the current Apple adverts.

I've kinda asked the same question in other ways in the past.

What I need: a blue or green background.
And use the chroma key tool.

Also: lighting is important.

I can do this... but I'm still stuck on how best to get a full length shot including feet: as they have in the apple adverts.

There needs to be a curve where the background meets the floor to hide the part where the floor meets the wall.

What the best way to achieve this?

In terms of the background material: will I be OK if I went and bought from my local fabrics shop?
I've seen on Ulead they have a background they sell... but this only covers the top half.

Lighting: not sure what to buy.
I've seen plenty of sellers on ebay who sell lighting with tripods.
What exactly do I need?
2 lights? 4 lights? (2 for the back and 2 for the front?)

Any advice would be really appreciated.
AND: any pointers where to buy from would be really good.
I'm based in UK... but would be happy to buy from abroad if necessary.

Thanks.
