floor joist/main beam replace

I have a 24x32 2 bedroom house. There has been water seepage into one corner of my basement for some 15-20 years (i'd guess) due to poor drainage on the backside of the house. In turn this has caused 6 of my floor joists to start rotting and the main carrying beam on one end to rot. The moisture damage is only in one corner of the house. The floor joists are 12 footers on each side of the beam BUT half the house, the floor is recessed so the 2x9 joists are sitting on top of each other with the rotten joist side on top of the other side joists. They are boxed in too which for the rotten side (maybe because they are sandwiched with the weight of the house on top??) makes things a lot! more complicated Im not no carpenter by any means but i DO have common sense and the ability to do things myself, and im confident enough to tackle it. Any advice on this would be greatly apprecited. Thanks Graham
PS- I just bought the house in december of 09.

Graham, Welcome to the Forum.
Jacking up a house to replace rotting beams is a major operation that requires a permit. Think safety, You don't want to be under the house cranking on a wimpy Screw Jack when the whole thing comes crashing down.

My advice would be first to get some professional advice. You don't want a speaker at your Memorial service to say that Graham thought he got good how-to advice off the internet.
