David,
If I read your post correctly, you have a complete set of hand drawn construction documents for a house that have been scanned into a pdf. You need someone to "create" a 3D model of the house using Chief. The amount of detail you would want in the model (cabinets, tile work, furniture, millwork etc.) as well as exterior (site, landscape etc.) would be a big factor. If you could post the pdf with your requirements I'd be happy to quote. I have been working with CA since 1995 V4 and currently use X8. I am located in the Denver area. I agree with DJP however - won't be cheap.
