Best Treatment for Gapped Teeth? (photo)

Hi, I have a gapped upper jaw, due to two missing inclsors (next to my two front teeth) I have measured the gaps and listed them below. What would the most effective treatment (Metal braces, Veneers, Bonding, invisaline etc) be and an approximate time line. Gap between two front teeth = 2mm Gap between left front tooth and canine = .5mm Gap between right front tooth and canine = .5mm Gap between left canine and bicuspid = 3mm Gap between right canine and bicuspid = .5mm .
