Rough Floor Plan Draft

Hi I need a REALLY basic draft of a floor plan, of a site on which I would like to put a small Subway store. The site is here in Hong Kong, rectangular in shape. I will provide you with a few photos which clearly illustrate where the shop is to be located. The sketch doesn't need to be to be to scale. In fact I would prefer if its a bit rough/ has a bit of character. No more than basic details of the interior of the shop are required. In fact the only interesting thing about the plan is the surrounding area, including an escalator which runs alongside of the site. Because its going to be pretty basic and not to scale, I would expect this to take less than an hour put together. Its not necessary to be in Hong Kong, although anyone local has the advantage of being able to have a quick look at the site if they wanted to (Queen's Rd Central). But its more than easy enough to work it out just by looking at the photos, which I will send you. The attached file gives you some flavor of what I'm looking for, although even this drawing is more detailed than required. * The next step will be a more sophisticated set of professional plans which need to meet council and planning standards.
