What I can offer you is a one on one meeting with one of Dane counties largest builders. We will help you put together a professional building plan with the cost per SQ ft being controlled by you. Would this be of interest to you. Contact me at http://www.chrislukenshomes.com
That being said, currently you could plan on a 2 story running between $110-$130 per sq. ft. and a ranch style upwards of $150/sq.
Again there are a lot of variable but this should give you a starting spot.
