The shelves are 36 inches wide. Is a stud finder needed, or are anchors fine?
Anchors rated for the shelf weight are fine on drywall. Maya's offer says she'll bring a stud finder and anchors, so either way is covered.
You have two offers: Maya at $95 and Jordan at your $80. Nothing is booked until you accept one.
