I second recommendation for Anthony Delcollo. Also, Delaware Association of Second Amendment Lawyers website has a "Contact us" tab. They were supposed to post a member's list, but haven't done so yet. Ask for members in your county. See http://www.DASAL.org
My guess is that they keep members names close to the vest, because of crackpot anti-2A and animal rights people. I was at last year's Annual Mtg. and anti-hunter had to be escorted out of the room! This year's meeting was limited to "Attorneys Only" . I didn't attend.
Also, be aware that Attorney General's office has an investigator to review applications (one of the reasons it takes so long, he's overwhelmed !- just my guess), so it may have been investigator's bias / opinion / recommendation to judge that got you denied.
