I have had a (very) similar situation, and I solved it at a very low cost.
1 (or optimally 2) DD-WRT Compatible routers (I use Linksys WRT54GS). Place the one at the internet source (office) and crank the transmit power way up. The unit may get a bit warm, so a simple small pc fan works great. The other end can be the same thing, but with the DD-WRT configured to bring the WiFi in and send it to the 4 Ethernet ports. Spread directional antennas through out the system and you have screaming internet system.
I was able to get my system to blast my network for over 1000FT, through an office building, with network slowdowns barely noticeable.
One note: make sure you get the older Linksys models with removable antennas. Linksys does sell a model of router designed for alternative firmwares like DD-WRT that includes many features to make this easier.
on a side note, it seems that someone ought to sell a package of all this set up together. it seems like a common problem.
