Beyond the framing, which is doable, just very invasive, the plumbing is a huge consideration. If you are on a slab it will have to be cut, and new plumbing(drain) lines run for the new kitchen. If your water feed lines are in the slab they need to move as well. Raised foundation is easier but still a lot of work, and clearance under the house is a big consideration.
As others have indicated, this is easily a $30K project. Once you get all of the infrastructure done all of the remainder adds up quickly.
