UPDATE:
So I decided to pay a visit to the local Bestbuy since they just got Magnolia and guess what, the guys over there were wayyyyy kooler then this builder's refered (forced) home theatre company. Besides all the great info they provided, they told me they can do the wiring for 5.1 with 12 guage wire for like 700-800 bucks, when the builder's company is doin it for $1250 with a 14 or 16 guage wire. The guys at magnolia also said they can do the prewire for the projector AND install the projector for like 700 bucks unless I want DVI (which i do), then it'll be like $300 more.
They said they will NOT create holes bigger than may be rougly an inch or so. And since my equipment rack will be in the corner which backs into the utility room which is unfinished anyways so thats a benefit too.
At this point, I have decided that I should get this done after i move in since the cost and the mess doesnt look THAT bad as i thought.
I am still open for suggestions guys and I do wanna say that if you guys hadnt pointed out the outrageous price difference and the other technical details, I wouldnt have gone to the other home theatre builders out there.
Now I can spend the saved money towards the RSW-12 or something
