Big factor is the labor cost. Try to ask some local contractor in your area or neighbors that experince these kind of works.

Depend on where you live. Get at least 3 quotes
I agree with the 30-50,000. On the east coast it is about $180/sq. ft. for an extension.

Good Luck.
Depending on where you are you are looking at approximately

19.750 to 25.500 if you have your own plans and it is passed by local authority
