Sources involved in the wedding tell us ... the ceremony will go down in Cedartown, Georgia and it will be a small affair -- close family and friends only.
That doesn't mean Sam's doing it on the cheap ... quite the opposite. We're told renowned Nashville bridal designer Olia Zavozina is all over the wardrobe ... she's designing duds for the men and a super expensive wedding dress for Hannah. She's also dressing Hannah's bridesmaids.
She recently designed Hunt's outfit for the ACM Awards.
The ceremony and reception will be videotaped, but we're told Sam and Hannah will NOT sell their wedding photos to any of the mags.
The couple got engaged in January ... so it's a pretty quick turnaround.
Wedding season has begun!
