Cost per sq/ft for Denver Pop Top

[Logan Star]

This is my 1st pop top and I'm curios what roughly I should be paying per sq foot for a 900 sq/ft house. I'm curious what the cost would be roughly with out a bathroom and what it would be with a bathroom. I know that this varies depending on many factors but I'm just looking for estimated of a range. 

If anyone has a good contract in Denver they can refer that would also be helpful. Thank you
