How to get building footprint drawings quickly

What are the best options for generating dimensioned footprint drawings of existing single family homes in Central Texas?
I have a customer in the construction industry who needs 2d drawings or sketches of private home footprints with reasonably correct dimensions (say with a +-10% margin of error).
The sketches should be in an electronic file format that can be redimensioned (allowing him to correct incorrect dimensions) and that allows him to add very limited elements along the outer perimeter of a home.
I've looked at using Google's SketchUp along with Google Earth, but I'm not sure this is a good way to do it - I haven't had much luck getting high enough quality images from Google Earth to work with.
I've also looked at services such as EagleView, but their service is specifically for roofers. Their reports contain a good deal of information that my customer doesn't need, and they're pretty expensive (up to $115 for a report on a large structure with same day delivery).
Some jurisdictions offer dimensioned sketches online, already, but Travis and the surrounding Texas counties don't. Travis county uses EagleView for tax assessment purposes, but it doesn't seem that they make this data easily accessible to the public.
In the best-case scenario, my customer would be able to quickly generate or order a sketch of a house before he visits the homeowner - quickly means with an hour of in-house work, or with one day of turnaround time from an external service, max.
Another solution that might be acceptable would be involve measuring (lasers, maybe?) the actual structure and turn the measurements into a drawing, quickly (on the scene, if possible).
My customer is willing to pay for a good solution that he could use in-house (Google SketchUp Pro + Google Earth Pro would be in his price range, for instance). He'd also be willing to pay around $10 per drawing to a company or individual who provides this kind of service.
