When I contacted my FSDO (they are a 3.5 hour drive away) well in advance to find out about inspection, I got this reply - basically - "We're busy, get a DAR."
This was OK by me because I wound up working with an absolutely great DAR, he helped me handle every aspect in advance so that the actual inspection went perfectly smoothly. There was only one DAR in my state that had the proper code to inspect for E-LSA as opposed to E-AB.
The reply was:
"Congratulations on nearing the completion of your aircraft. The FAA has
put a network of Designated Airworthiness Representatives together that are
able to assist you with your request. These DAR exist to allow FAA
Inspectors to concentrate more heavily on the oversight responsibilities
they are assigned. Although there is a cost associated with using these
DAR, the assistance they can provide during the certification process is
invaluable. I would suggest you contact one now, as you are contacting us,
to move forward in a timely manner. Please follow this link,

to access the list of DAR in Arkansas. Please note that not all DAR may
have the appropriate authorizations to assist you in your certification
project, but most are. You may want to invest a bit of time interviewing
each to find one you will enjoy working with. If you have any other
questions, please do not hesitate to contact me."
