I am a local architect here in Paulding County. What you need are what we call "As-Built" drawings. Typically for houses that are older these are either lost or non-existent. Architects do offer services that come out, measure your entire house, then draw the existing plans according to those measurements. If you need any help with this, please let me know. I just started my small business recently and trying to get plugged into the community. Check out our website: www.radga.com for more info.
Hope this helps!
