I think brickforge should advertise their products on say, a billboard on a main highway or on cars and TV. Also, There should be Brickforge retail stores, examples include shops in malls.

That's... extremely unlikely to happen. Sorry dude!
There's so much involved with that, and I don't doubt Brickforge could handle it, but it just wouldn't be feasible mainly because as many FOLs as there are in the world, they're still just a percentage of the population, and people who use custom parts are a percentage of that percentage... see what I mean? Plus there's costs to that, which, I'm not gonna say they couldn't pay for themselves, but it's probably not The Next Step.
Thanks for your interest though.
