Sadly the whole point of avoiding ST is avoiding the biggest image from a given distance..the higher gain screens work best with a long-distance narrow beam..or a shorter distance narrow beam, which results in a small image (typically around 50"-70" with only a 10ft throw distance.
Because you're going big within 10ft or less, you'll either need some decent lumen muscle and a very good rear-projection setup like discussed in the previous thread, OR a fairly plain screen and a massive wallop of lumens for front-projection.
I remember you expressed interest in taller ratios like 3:4 instead of 16:9 and I've read there's a lower resolution NEC um330x ultra-shortthrow capable of nearly 4000lumens at 4:3 which sells around $1000 with replacement lamps only costing $79. It should be bright enough for a 8ft-by-6ft 4:3 screen in a lit room.
There don't seem to be many ST projectors that are measured quite this bright it seems..I'm not sure if the 768x1024 resolution would be too low for your needs.
I'm sure there are other options, but NEC is a respected brand, the lamps are cheap, the lumens high and the throw is very short in case you have anyone walking inside your booth.
