Photo shop help needed

[Bluecab]

Hey there photoshop guys!
Can anybody help me with this? I'm looking to fill the whole insert in the tail with custom made taillights and relocate the plate to a recess in the bumper where the backup lights are now.
I will also do the bumper body color...



Any assistance will be greatly appreciated as I have no photo shop on my computer and no skills even if I did. Just looking to see if the idea I've been playing with would look any good.

Thanks,

Bluecab
