damnit man! I just wrote a response and it freakin Timed out on the webpage so I gotta re-write it.
Yeah I live in california. I designed, maintain, and help run my dads online business so I know all about shipping and customer service although I'm sure you would think otherwise regarding customer service
My case is probably heavier than most cause I got a lot of fans and did major case modding to it, so it weighs atleast like 30lbs easily and that's probably anywhere between $15-$20 to ship.
Dell and peoplePC ship computers all the time, so as long as you package it good, shipping it cross country shouldn't be a concern. I'd build the computer for you as I'm sure a lot of other people would to. But it's a matter of getting the parts here to put together then sending it back to you. The best bet would be to order the parts to whomever is to put it together and have them ship it back
My father and I own:
It's a home decor site, but the point is, I can help you out if you need. I'd create a 'product' which I would make it so that no other customer other than yourself would be able to find, and would be able to calculate shipping fee's through that. As for paying someone to actually put it together, well half the fun is powering up that beast and seeing what it's capable of. Other than that, simply putting a computer together isn't worth a WHOLE lot of money. I'm sure places like best buy or local places would charge $100 easily so maybe look at what other places would charge and make a decision based on that. PM me through here, or contact me via my website if you want to work something out.
