Took me a while but Ive got it now.
When adding their contact, I put a heart emoticon before their name. This groups them all at the bottom of my contact list (ironic, i know). This way I can easily "sort" them and scroll through who I want to contact. Now they aren't lost in my other contacts throughout my iPhone and are now easily findable.
