You have the pattern for what you want right there. Take the photo you have and adjust the scale of it in a photo edit software to the tile size you want. Print on glossy photo paper. Then cut the "tiles" and glue them to the "floor" of the showroom. Seal the edges down with either a clear coat of Future floor wax or lay in a thin coat of clear epoxy resin as used for making ponds, streams etc. Why pay for someone else to manufacture when you can produce it at home.
You can also add realistic "carpet" to your show room offices. I copied a full length photo of a persian rug from the net and printed it out on matt photo paper. A quick shot with Testors dull coat to add "texture" and to fringe the edges I used a piece of yellow nylon. I glued it to the underside of the "carpet" and then pulled the loose fibers until I was left with only half the original piece with the remaining pieces forming the fringed edges.
Yes, I am full of information as you can see. Most of my friends have stated they will have me listed as their "Phone-A-Friend" for Who wants to be a Millionaire. Seriously though, I just like to learn new skills and have been gathering an extensive reference collection for modelling. The great thing about this hobby is that no matter how much comes out in the aftermarket "off the shelf - stick it in and you're done no skill required" sections it really is satisfying when I can look at the completed work and know that I created the piece and there isn't another like it.
Anything further you require, I'll be happy to assist.
Cheers;
Gregory
