Need help modding art for HORI REAL ARCADE PRO 3

Hey everyone, I recently purchased a HRAP3 and am about start modding it, i have purchased sanwa buttons and am getting a new gate soon, i want to customize the artwork but i do not know what to put, i have been searching for outlaw star, cowboy bebop, and cammy and blanka art, but i have yet to find any of the first two, i found a FLCL one which was cool, but i really would like to find an outlaw star art template, i do not have photoshop so i cant really do this well on my own, so, anyone got any info that may help? I will be very appreciative, thanks!
