Google SketchUp and about 2-3 days of full work LOL (part of that was learning the program though).
What is great about SketchUp are the community models. MOST of that layout is just using the in-program search feature to find objects (like the pool table, couches, toilet etc).
Once I got some feedback from you guys, I adjusted the layout easily. Moved the pool table, added some seats to the game area, put "bricks" on the wall etc.
Only drawback is the lighting. By default it only has the sun - unless you buy plugins. Therefore the ambience is off. I want it to be darker and allow the screens and some of the wall lighting to accent the place. But C'est la vie.
At least this may help in securing a loan. God I hate being poor and having to support a family to boot. ><
