I need a sketch of a conference set

Hi, we are a conference company. Our Set Designer has gone sick, I have client meeting on Thursday morning. we have dimensioned drawings of the conference room, and hand-drawn (by us) plans of what the set will look like. we need 3 visuals, (in the old days they would have been called magic marker scamps) as "Artist's Impressions" of the 3 different options on sets.
I will pay £100 to 2 designers for first stage line-drawing scamps. I will then pay another £100 to the best designer for coloured versions. Starting now, need finished coloured versions on Wed evening please. sorry for late notice. Andy
