A cantenna with a reasonably high-gain antenna is a good bet, but it could be pricey. Linksys makes some routers that are compatible with ww-drt firmware that will also allow you to adjust the power output of the router itself - however you will need one on both ends.

It might be cheaper and easier just to get the team to sign up for a couple of months with a broadband wireless card and then run your internet through that. Generally the cost about $59 a month. Have you checked to see if you could sign up for two months of DSL or Cable internet?
