Need help with tattoo placement and suggestions on my ideas read additional info (10 easy pts best answer) ?

Ok so I've been thinking about this tattoo for almost 10 months and I need help deciding... And need help with where to get it I WANT TO BE ABLE TO SHOW IT EASY BUT BE ABLE TO COVER IF NEEDED... Here is some info on the subject... So my sons name is Keegan and its Irish and Gaelic origin and means "small flame"....Ok so my birthday is friday and I'm getting a new tattoo. :) I have a pink and black nautical star on my left foot already, so no more foot tattoos..but I want to get something in honor of my baby boy who is 9 months old... My ideas are the roman numeral 27 (XXVII) which is the day he was born, and maybe incorporate his name (Keegan Lane).... I can't figure out where to get it though.. NO HAND OR FOOTPRINTS I also was thinking of getting a crown like the Juicy Couture one on top of the (K) for Keegan or on top of the (x) for the XXVII--27 in roman numeral..... Suggest please.
