I think going on what popa said:
If you just find ANY FBO that operates a seminole such as http://www.pinnacleacademy.com/multiengine.html (I have been there and they are a very well run and professional establishment) In the west you should be able to complete your training regardless of the situation in under 2 days if you just buckle down and do it. If you fly 2 hours in the morning, 2 in the afternoon and study in between there should be no reason why any FBO wont be able to get it done for you in no time flat and finding 1-2 days with good weather shouldnt be too much of an issue for most anywhere in the country.

Check out Pinnacle though and look at their fleet and click on their seminole, it is a very well maintained and nicely equipped twin, pricey, but nice.
