Modeling is really not that hard, it just takes a long time to do it well...
Now you say you've posted 10 "great ideas" and that loads of other people have posted greeat ideas too... well it works like this:
We as addon makers, make what we want to make, not because we don't like your ideas, but that we're doing the hard work so we want to see something ingame that we like, and will use, not something that we spend hours making, and then never use ourselves (were not getting paid, so there has to be a perk in their somewhere)
Prior to the release of O2 i had never even looked at a 3d modeling tool...
I was in the same boat as you, posting request after request for this and that - and especially one thing: an MH-60 with the M134 minigun, now, a few months later, i am working with one of the biggest and most respected addons teams there is (no prizes for guessing who - BAS...) and I am making that addon...
So go and download O2, and see what you can do - to get some of your ideas made into realities (btw, sorry for the cheap O2 pun - any brits will understand me :p)
and another btw, modeling with O2 really isnt that hard... there are a lot of high quality tutorials out there, so go on - learn to do it
